RE: about XML 1.1 (was: Re: new issue? dfxp and language selection)

One correction, DFXP is most certainly not restricted to "just ascii" it is based on XML Character data which is : " an atomic unit of text as specified by ISO/IEC 10646:2000 [ISO/IEC 10646]. Legal characters are tab, carriage return, line feed, and the legal characters of Unicode and ISO/IEC 10646."

I would however be willing to adopt XML 1.0 (5th edition) as the XML reference. If others have no objection.

Except .... a friend tells me gives the following feedback:

"XML 1.1 is a failed experiment that it isn't supported in Gecko, and
even the W3C is giving up on XML 1.1. The element and attribute name
internationalization aspect of XML 1.1 is moot when it comes to DFXP,
since DFXP elements and attributes are ASCII anyway. The expansion of
the meaning of whitespace in XML 1.1 is a reason to stick to 1.0. The
reference to XML 1.1 Name production for extension-role could be
avoided by specifying that the extension token is any string without
whitespace in it. (I'd prefer to see DFXP reference XML 1.0 instead.)"

With XML 1.1 not being supported by Web Browsers, we severely restrict
the parsability of DFXP and therefore the potential for uptake. Do we
have amongst our trial implementations anyone who is implementing
support in a Web Browser? We've got to seriously consider DFXP as a
solution to Web Video accessibility.

Silvia.
