Subject: Re: ALT attribute & Conformance levels
Before we label "levels" to various browsers, I think it'd help if we,
the Web community, collect and maintain some basic information about
different browsers.
Up to a point, I think labeling browser conformance levels is roughly
like viewing evolution as a ladder, rather than a branching tree.
Sure, most browsers now share lots of common functionality, but there's
going to be specializations.
But I agree that some basic set/group/level designation is very useful.
So, how about we flesh out a "WWW Browsers Capabilities Tabulation" chart,
then group the capabilites into some conformance designations. Such info
is useful in anycase-- as you can see below, I'm no longer sure of what's
in what browser.
Keys:
a = available for use.
e = experimental status. in development but unstable.
i = incomplete implementation.
u = unavailable to public (yet), but exists.
