Why the word "should" is being used? This allows implementors to simply
not implement this, therefore not providing authors a way to check for
HTML 5 support (WA 1.0).
It's a "should" because in some cases, e.g. experimental or incomplete
implementations, the UA implementor would want to specifically return
false so as to not make this mechanism useless.
Given my email was written loong time ago, I had lots of time to learn
about what HTML 5 is, what Web Applications 1.0 is, and generally about
web standards.
Thus, now I agree with the wording, yes "should" is correct. Anne van
Kesteren has provided me with valuable feedback in November 2005.
b) The feature string "XHTML" combined with version string "5.0" is to
me not very inspired. Simple reason: XHTML 2. What if they get to XHTML
5? In my opinion, checking for XHTML 5.0 should *not* be available.
Are you still worried about this?
No, not at all. I didn't estimate WA 1.0 will ever become (X)HTML 5.
I'd like this to be available, because as a web developer I'm interested
to check in general if the user agent supposes it has support for WA
1.0. When I want to do a general check I wouldn't like to write a huge
script which checks the availability of each of the WA 1.0 DOM stuff I
use.
You can check the feature string, that's why it's there. But it won't
tell
you much. Browsers don't support HTML5 or not support HTML5. They support
bits of it. For example all browsers support <div>. But no browsers today
support <datagrid>. What should today's browsers do when queried about
whether they support HTML5 in hasFeature?
Well said. Now I agree and I better understand the reasoning behind the
choices made in HTML 5.
Thanks again for the feedback.
