You might want to take a look at XSchema's XSchema element - we used a #FIXED Version attribute in the DTD to identify that all documents using this DTD are using version 1.0 of XSchema. When we develop another version, we can create a new DTD and update the value to 1.1 or 2.0 or something else more interesting. (Schemas created using XSchema will need to implement their own versioning mechanism, possibly using this same technique in their root element.) It's only guaranteed to work in a validating environment (where we can count on the parser to read in the external DTD and apply the value), but it's pretty convenient. (The XML spec only provides for XML's own version functionality.) Hope it helps!
