non-deterministic simpleContent restriction definition

Hej,

to validate the occurrence of xml tags for schema input the most elegant way 
is to use a DFA according to the regular expression given in the XML 
Representation Summary in the schema spec for every component.

That works fine in schema 1.0, however with schema 1.1 and the introduction of 
assert, the regular expression of the simpleContent restriction isn't 
deterministic any more. If you encounter an 'assert' tag, you don't know 
whether it is the one in the group of facets or the one at the end.

Any chance to get back a deterministic regexp here again for the final 
version?

Ciao,
Tobias
