One issue you should consider is development time. It's pretty easy to slap together a dtd, it takes a little more work with a schema. What I think you should do is consider:

* your current needs (if you don't need to use schemas, don't)
* your future needs
* development time
* tools
* support
* learning curve (for me, DTDs are a lot easier to figure out than schemas)

I'm thumbing through the XML Bible, and on page 829, it says "...schemas are not a be-all and end-all solution. In particular, schemas do not replace DTDs! You can use both schemas and DTDs in the same document. DTDs can do several things that schemas cannot do, most importantly declaring entities." mmm, that's interesting, I actually didn't know you could use both, but I suppose it makes sense.
