Dear Synchronized Multimedia Working Group,

  http://www.w3.org/TR/2005/PR-SMIL2-20050927/ section 13.3.2 requires
that SMIL 2.1 documents conform to XML 1.1; this seems to be a result of
global search and replace, there are no references to XML 1.0 anymore.
This is an error, while it'd be good to say XML 1.1 may be used for SMIL
2.1 documents, requiring that implies that XML 1.0 must not be used for
SMIL. Considering that XML 1.1 should be used only if really needed,
this is a bad idea.

A related problem would be that various types like NMTOKEN, IDREF, etc.
are defined through reference to XML 1.1; in an XML 1.0 document however
attributes of these types cannot use the XML 1.1 syntax and would not be
valid; this essentially means that one part of the prose allows use of
the extended syntax while the other part prohibes that. This can be
worked around by not using the various types in the DTD and just rely on
CDATA, but that might not be the best solution.

regards,
