Re: [whatwg] What exactly is contentEditable for?
I've been following this thread for a little while. I too think that the contentEditable is not done quite right. My biggest problem with it (and this was pointed out before) is that it is a half-way effort: there is markup that enables the editing, but there is no markup that provides any information about submission for the edits. IMHO, this is incomplete. If you provide means for entry, it shall be your responsibility to provide means for exit. I was surprised to learn that WF2 spec does not support rich textarea. I still can't figure out why. Again, IMHO, the contentEditable attribute represents a shift of paradigm in Web markup: it suggests that the actual markup of the page could be the target of user manipulation. Prior to it, users were confined to forms elements. It's not that I mind the shift. But this shift is kind of huge, and I don't think it's wise to shift just bits and pieces. :DG
[whatwg] Conformance requirements on conformance checkers
Quoting from http://whatwg.org/specs/web-apps/current-work/#parsing : Conformance checkers must report all parse error conditions (both hard and easy errors) to the user, but may apply error correction algorithms (those described in the spec for easy errors, and those reverse-engineered from other UAs for hard errors) in an attempt to continue past the location of the error and find the remaining errors. The latter part of the sentence somewhat implies that the parser might not be required (in the MUST sense) continue to find all errors. However, the start of the requirement could be clearer. I'd prefer something like this: Conformance checkers must report at least one parse error condition to the user if one or more parse error conditions exist in the document and must not report parse error conditions if none exist in the document. Conformance checkers may report more than one parse error condition if more than one parse error conditions exist in the document. Conformance checkers are not required to recover from parse errors (not even easy parse errors). Rationale: Considering the purpose of a conformance checker, it should be sufficient for the conformance checker to find out whether the document is conforming. Additional reporting should be a feature bargain between the conformance checker developer and users--not a hard spec requirement. Besides, XHTML flavor conformance checking is likely to stop on the first well-formedness error anyway. -- Henri Sivonen [EMAIL PROTECTED] http://hsivonen.iki.fi/

[whatwg] WA1: li processing
# If the attribute's value cannot be converted to a number, it is treated # as if the attribute was absent. The attribute has no default value. The attribute's value is treated as if the attribute was absent doesn't make a whole lot of sense to me. Did you mean a different 'it'? # The value attribute is processed by the parent ol element, if there is one. # If there is not, the attribute has no effect. The first sentence makes no sense. What does it mean for an element to process another element's attribute? I thought the UA processed the attributes. Is the second sentence meant to imply that when the parent is not ol the value DOM attribute reflects a missing 'value' attribute rather than whatever value the 'value' attribute actually has? If so, you should make it more explicit. If not, you should make /that/ explicit. # Each subsequent item in the list has the ordinal value given by its value # attribute, if it has one, or, if it doesn't, the ordinal value of the # previous item, plus one. The instructions in the ol section seem to omit any reference to the number conversion step described in the li section. Here's a suggestion: Replace # If the value attribute is present, user agents must convert the # value to a numeric type, truncating any fractional part, in order # to determine the attribute's value. If the attribute's value cannot # be converted to a number, it is treated as if the attribute was # absent. The attribute has no default value. # # The value attribute is processed by the parent ol element, if # there is one. If there is not, the attribute has no effect. with | If the value attribute is present, user agents must convert the | value to a numeric type, truncating any fractional part, in order | to determine the attribute's numerical value. If the attribute's | value cannot be converted to a number or the attribute is missing | (or the parent element is not an ol element)?, then the attribute | has no numerical value. and # Each subsequent item in the list has the ordinal value given by # its value attribute, if it has one, or, if it doesn't, the ordinal # value of the previous item, plus one. with | Each subsequent item in the list has the ordinal value given by | its value attribute's numerical value, if it has one, or, if it | doesn't, the ordinal value of the previous item plus one.

You altered WF2 to make it repeat aspects of what he wrote (CSS3-UI). Obviously the person who wrote the sections of the CSS3-UI spec you're drawing from is going to agree with corrections that reinforce his own content. Ok, I'm glad you agree that it reinforces CSS3 UI and doesn't conflict with it. That is what was intended. We can't really do anything else, since CSS3 UI isn't one of the specs WHATWG is doing. What was wrong with the revision I suggested?... | Matches form control elements that have the readonly attribute set, | and to which the readonly attribute applies (thus radio buttons will | never match this, regardless of the value of the attribute), as well | as other elements defined by this specification that are defined as | read-only under the CSS3 Basic User Interface Module. Well, the second part doesn't say anything (it's redundant with CSS3 UI). The whole point of the section is to say which elements defined by WF2 match the definition of CSS3 UI. In a scenario with script, when would you disable the input readonly element specifically and in markup rather than disabling a parent fieldset? There might not be a parent fieldset. In any case, what's the difference? So, when am I going to need to disable a single read-only control independently of other controls? Not seeing a use case here. One possibility would be viewing a database view where the user has rights to edit a field on some records but not others (e.g. allowed to edit the customer's start date but only if the customer hasn't started yet). As you flip through records, the field becomes read-only or not. It's not disabled, because the data is still relevant, even though it can't be edited.

So contentEditable is more of a compromise between the original intent of the Web and the don't let them modify it! attitude that has grown since. I understand (and appreciate) the sentiment, but that's not how HTML had developed. Amaya's simplistic PUT is not going to cut it for most of today's managed content. Web pages have become compositions of resources, and something a little more sophisticated is needed to specify how the edits are passed on to the server. As you know, there is already a scheme for communicating server's expectations on input -- forms. I can't see how contentEditable fits in this scheme. The attribute only specifies whether the area is possible to edit. It does not specify how the UA is to communicate it back. It just doesn't seem kosher to leave it as is. And answering your earlier comment, I understand that it's just a couple of lines of code to provide that communication. The problem is that it's not a consistent or standardized way, which makes it next to impossible to determine how this communication is handled without actually executing the code. Shooting from the hip, I would rather see something like this: textarea type=text/html src=#mainPageContent id=mainPageContentEditor/textarea Where the src attribute points to an element (or the whole document, if you want to). The element and its children/descendants may or may not have contentEditable attribute set, thus regulating which parts of the fragment is editable. At least now you are using the same form scheme to specify how the server would like to receive this data. :DG

That's a reasonable argument for standardising the DOM interface for it, but not for including contentEditable as an attribute in the markup, which is what I'm against the most. Although I am against the use of contentEditable in general, that's mostly because {a) all the implementations of it are broken and (b) the way it was designed is too presentationally oriented for a semantic markup language - it basically suffers from the same design flaws as every other WYSIWYG editor. Using the wiki example, a script could be provided which captures the events for the edit this links and dynamically makes the content for that section editable using the contentEditable DOM interface. Scripts would also be used to handle the submission. However, without script those links should fall back to the way they currently work, which is to load a seperate page with the editable markup in a textarea for the user. Additionally, that textarea could have an accept=text/html attribute, from which (even without JS enabled) the user agent could choose to load an HTML editor for the user (whether that be for just providing syntax highlighting in code view or a WYSIWYG style editor). Personally, I'd like to see it better integrated with the DOM 2 Range interface, so the scripts could work with the nodes a little easier and which I'd like to see more widely implemented. -- Lachlan Hunt http://lachy.id.au/
