<excerpt>One important question that's bound to come up is whether to
enable this

for just XML languages, or all formats; i.e., whether it's desirable to

come up with a URI-based typing system for the Web. My inclination is
to

limit it to XML; although the registration process for media types can
be

onerous (and there are signs that it's improving, BTW), it does serve a

purpose. I don't think the community would be served well by an
explosion

of formats if there weren't a common thread (such as XML) that runs

through them.

I agree XML only.


<excerpt>Another issue is that which Don brings up; how to identify a
specific

format. My inclination is to only use a URI, as URIs are first-class

identifiers on the Web, and anything worth identifying should have a
URI.

That having been said, there's no regular way to turn a QName into a
URI

[1], which I think is what Don wants to do. So, in the meantime, we
could

do something like

 XML-Dialect: "http://example.com/foo.xsd"; localname="Bar"

making the localname parameter optional, so that we can drop it once
the

QName mapping issue is solved to everyone's satisfaction.


</excerpt>

This would certainly be sufficient for our requirements.


<excerpt>This also has bearing on TAG issue 9 [2], and should be
considered in that

context.


I'll endeavor to put together a first draft and circulate it ASAP.

Thanks again for your help with this - I will circulate this proposal
within Liberty as a potential solution to our problem.
