Hola,
I see that the Creative Commons has proposed additions to HTML

Just so I understand you, are you saying that attributes aren't markup?
Because first you say "no new markup", then you list 5 attributes to add.
Ah, sorry for the unclarity. Attributes are markup. The sentence comes
as a whole: I meant that ccREL proposes no new *CC-specific* attributes
or elements. They get their job done using general RDFa markup.
Second, the Introduction cites RDFa, which footnote 4 describes as "an
emerging collection of attributes and processing rules for extending
XHTML to support RDF". However, the Introduction text and example go
on to talk about HTML. Independent of any other discussions, I think it
behooves the authors to clarify their intent. Is this for XHTML, HTML or
both?
Yes, this could be clearer. The group's general line (Ben feel free to
correct me) is that this attribute-driven markup style is intended to be
largely neutral of its 'carrier' format, but that RDFa-in-XHTML is the
only version that is fully specified with implementor tests etc
underway. For this markup to work in other XML languages would require
some more work; for it to be deployed in non-XML HTML (HTML5 etc)
requires even more. But the general notion is that these attributes
could be deployed in SVG-based, HTML5/6-based etc. languages too, ie.
that this isn't a project tightly bound to (some specific version of)
XHTML. Of course in a non-XML context, some other mechanism is needed
(eg. link rels) to associate abbreviations with URLs.
Also in http://www.w3.org/TR/rdfa-syntax/ (now in CR at W3C,
http://www.w3.org/TR/2008/CR-rdfa-syntax-20080620/)
[[
RDFa is a specification for attributes to be used with languages such as
HTML and XHTML to express structured data. [...] This document only
specifies the use of the RDFa attributes with XHTML.
]]
Does that help?
cheers
