(So why have you started this list with level0 instead of level1... just
curious. ;-) )

I suppose this would make it clear how much TEI your document is... I'm assuming
(as I think you have done above) that having an ODD-derived schema is 'better'
than just using TEI element names.  Your levels do mean that if I delete the TEI
namespace from the TEI element in a document instance, and so it is also no
longer validated by my schema, that I instantly jump from level 0 to level 5.

Then we should have these levels above also start on 1.  :-)

In that case, I only find it highly desirable. :-)
