hi,
someone I'm working with will soon be arguing for wholesale adoption
of the CCTS NDR and using as their argument that users will be able to
generate schemas just by writing models as opposed to having to deal
with the complexity of schemas.

This seems pretty wrong headed to me, but I must admit I am not
knowledgeable enough about CCTS NDR and the modelling thereof to know
how advanced any applications for doing this modelling are. I am going
to assume not really too advanced.

An especial quibble I have is, yes it may generate schemas from models
but will schemas generated from models be able to work in a broad
cross section of processors. It seems somewhat wrong headed to expect
automatic execution of schemas from models when processors for schemas
often have a lot of incompatibilities.

I am also more apt to think that writing code is preferable to
generating code, partially caused by the experience I have that making
the models is as complicated as writing the code in a lot of
instances.

Cheers,
Bryan Rasmussen
