Re: Flexible config (was Re: Action threadsafe)

True, schema is pretty verbose, but personally, I don't mind since it is 
a one time thing users wouldn't have to worry about.  Another benefit is 
we could define a doc namespace, and include all of our config 
documentation withing annotation/document elements.  An XSL stylesheet 
would pick up our doc namespace elements and convert them into nice, 
multi-format documentation.  (I say custom namespace to allow us to 
define docs in a limited taxonomy to improve the quality of our output 
documentation.)

Technically, moving to XML schema would be easy :)  I wonder why we 
use DTD now.  If it is Java support, you could use a supplemental

in the end, schema would be a huge simplification IMO)

There was a time when Struts depended on a validating parse against the 
DTD to fill in default values; those have all been factored out.

I prefer RelaxNG to XML Schema, but from a bit of searching, I'm still 
not clear about how to validate in a universal way.  I've used the Sun 
Multi-schema-validator with it, but I'm not sure that we can expect 
everyone's JAXP implementation to be able to validate against RelaxNG.

I was excited about XML Schema for a few weeks, but I soured on its 
verbosity; still, it's probably better than using a DTD.
