That's not what I'm thinking of. My application might require data that follows a DTD,
but I might not require incoming data to include the DTD (or even a reference to it).
There are XML formats (e.g. XML-RPC) around that are precisely defined, but not
with a DTD. I can come up with a DTD for them and validate conforming data that,
of course, doesn't include or reference a DTD.
Also, by separating DTD parsing from validation, there could be a way
of using schema data in other formats (e.g. RSS schema?), as long as
the other formats could be parsed into the same data structures that
DTD's get parsed to.
