Michael's convention is essentially just markup minimization. In full
SGML, he would actually use markup minimization to force the #PCDATA into
its own logical element (even without tags).

Nevertheless, I see no good resaon to restrain him from doing this. Markup
is a user interface and we need not make it unnecessarily unpleasent. XML
DTDs do not allow PCDATA content at random places because of whitespace
handling problems and backwards compatibility. I do not think that XSchema
has any such constraint. #PCDATA should probably be able to go anywhere an
element can go, unless someone can come up with a strong reason why not.
#ANY should also be able to go anywhere an element can go. This will allow
the natual expression of extensible content models.
