I can forsee applications where one might say, "Please send me documents
conforming to the FOO schema," in much the same way as one requests
LaTeX or Word formats these days.  In which case, one usually needs also
to specify the root element (this is implied in LaTeX or Word).  I don't
see any harm in the schema having a default root (on the understanding
that documents may, if they wish, use a different root).

It's not a big issue to me, though.
