A separable part? Other than Jeni Tennison, I haven't seen any uptake on
this issue.
At least relax ng allows data type plug ins.

Unless you use relax ng tools to convert to xsd?

my schema validation gives me, not as a replacement? Rick?

A single stage validation is helpful, rather than pipelining.

I guess we aren't 'the world'.
