Thanks Lisa,

I didn't really have a particular question. I'm starting a new project in which we plan to do XML exchange. However, I'm pretty much defining the standard of what will be used/passed, etc. I wanted to be sure that I was validating the XML being sent to me but I wasn't sure whether I should be using DTD or XSD.

It sounds like they're pretty much competing technologies where you use either one or the other but not necessarily both.

Thanks again for your input.
