Elements and attributes are not optional in XML 1.0.  You are confusing 
optionality with
syntactic sugar.

What does that mean?

Support for parameter entities is optional, in the sense that a 
non-validating parser that finds a
document with standalone="yes" does not need to process the external 
subset of the prolog.

There is no such thing as a PI entity (even in SGML). There is no such 
thing as a Schema entity.

If you go to Wimbledon, it is useless to sit at a court where the match 
has finished and
demand a rematch to the empty stadium. You have to go to the court where 
a game is
still being played. In XML's case, the games being played at the moment 
are the fast
infoset and the XML pipelining work.

How ridiculous.

If there is an XML 2, it will be a consolidation of the existing pending 
fiddles that are
floating so fecklessly about at W3C, in the light of a stronger 
processing model that
gives some meaning to them: XML 1.1 - DTD + namespaces + xml:base + 
xml:include
+ xml:whatever + processing model.

There will be that XML 1.0, XML 2.0 as above, plus a binary version, 
plus JSON, as the dominant players, AFAIKS.
