[tei-council] customization in P5

[Syd Bauman]

Sebastian, do you realize that we're talking about customization
here, not creation of schemas? Your arguments seem to be discussing
the latter, so I wanted to check that we are on the same page before
I responded at length. The question at hand is whether or not we
should support users writing customizations in:

* ODD	       (of course)
* RelaxNG      (I think so)
* DTD
* W3C Schema


Although your last paragraph does seem to be about customization, so
I'll address it now.

I'm not sure what you mean by the RelaxNG parameterized schema
fragments, but dropping the parameterization of the DTD fragments
would be a Good Thing. I think creating them has been a waste of your
valuable time, as will be maintaining them in the future.

Has anyone tested this? I will buy you a (cheap American) beer if it
does not turn out not to have problems, and there are not lots of
customizations that are trivial in ODD that are difficult in DTD.
