While an interesting and potentially valuable idea, this is
the kind of thing that profoundly alters the requirements
on programmers -- in essense it means that in addition to
writing a parser for CTM they must also provide support for
XML fragment parsing and validation (which is markedly a lot
more work and also decidedly different than XML document

One might want to consider the impact this proposal would
have on implementations. It certainly raises the bar to
entry considerably and would require both an EBNF for CTM
and another for XML. With XTM 1.1 at least the parser was
already available.

My initial reaction was "yikes!"
