Model group ambiguities

[Helmut Lutzenberger]

Hi,

 I read something about model group ambiguities, saying things like:
(item?, item) are ambiguous and are therefor not parseable by an
XML-parser.

My question is now; model groups are regular expressions and every
regular
expression is equal to a nondetermenistic automat and with
Myhill-Nerode it
is possible to build an determenistic automat equal to the
nondetermenistic
one. So I thing it should be possible for the XML-Parser to eliminate
such
ambiguities automatically, without too much trouble. Or am I wrong?

-Helmut
