Thanks. I'm using DocumentSchema.NO_SCHEMA_CONSTRAINTS for now.

I would say the simplest approach for you would be to provide a schema
that allows everything to start with, so you're free during
development to do as you wish. The purpose of schemas is to guarantee
certain constraints on the XML, so strange cases of malformed data
don't have to be explicitly handled in the code, which makes things a
lot simpler. I.e. their purpose is to make the code simpler - if it's
just a bother for you then I'd advise you just use the null schema
which I believe is defined as a constant somewhere.

Hi Daniel,
I'm currently playing with the editor harness and would like to
express contraints for a couple of schemas. So I didn't quite
understand what you meant when you said that schema validation
should run on the server. Should I just use no schema validation
on the editor ?
I'm perfectly ok with droping some validations and I'd sure prefer
going with a script of my own. I'll look into this and try to find
something that integrates properly with the build tool chain.
Regards,
Nelson

Hi Nelson,
You'll probably find that XSD, RelaxNG etc can express a lot
more constraints than are possible in wave schemas, because
some constraints don't play well with transform (we desire the
property that two schema-valid operations are still guaranteed
to be valid after transform, and so things such as sibling
relationships aren't possible to enforce). Thankfully,
parent-child relationships are expressible.
That said, as long as you're happy for the generator to drop
certain validations that are too strict, then this sounds like
a cool idea.
I don't know if anyone's tried this before. But I would ask,
why bother with a GWT generator, as opposed to anything else
that could spit out java code including a hand-rolled script?
In any case, if you have schema validation at all, you'd want
it to run on the server, where there's no GWT.

Dan

Hi all,
I'd like to be able to use a schema (XSD, DTD or RelaxNG) and
produce a DocumentSchema. I was thinking of using a GWT
generator
to create the necessary DocumentSchema subclass at compile time
but would like to know if anyone has done anything similar
before
doind this.
Thanks in advance.
