Well, its kind of a practical matter. From a support perspective (kind o'
important to a company our size) proving that the content model is ambiguous
means never have to say you're sorry, or at least have to say you're sorry less
often. We don't want people pounding us with suspected bugs that are really the
result of ambiguous content models. The existing DFA system makes it quite
straightforward to catch this, and anything that makes it hard is a bad thing,

And, before anyone calls me on it... no the existing XML4C2 out there now does
not do this check! It'll be in the next one :-)
