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 library for Java 1.3 or earlier. Perhaps it is complexity? (although 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.
