Re: [xml-dev] Was there a technical issue for the demise of XML 1.1?

Hmmm,  I am not sure that a technology that does not get taken up can claim to be much of a success merely because its spec says "Don't use me if you don't need me", can it?   But "don't use me" is a bold step forward in conformance clauses :-)

I have a different view to share.

Quoting chapter and verse, the XML 1.1
specification states here that if you are not
using a feature of 1.1 thou shalt use a declaration of 1.0:

   https://www.w3.org/TR/2006/REC-xml11-20060816/#proc-types (last paragraph)
  "Programs which generate XML SHOULD generate XML 1.0, unless
   one of the specific features of XML 1.1 is required."

Okay ... so it isn't "SHALL" ... still, I think
the compulsion is there in that statement. And so
I told my students that all XML 1.0 documents are
XML 1.1 documents, they just aren't using any
features that are unique to XML 1.1 and so are merely declared as 1.0.

And to another point made in the thread, #x00
isn't valid even in XML 1.1 and so some desired
binary sequences are still not possible in XML:


I hope this is helpful.
