Perhaps I will have to learn to read C++ sooner than I had wanted to. :) Is there a DTD?
Well, there isn't. This is partially for two reasons:
- I'm lazy
- I don't know how to (see 1)
If you'd write one, I'd maintain it as I make changes to the format (should be pretty stable at this point though). I think that I've heard XSchema is better, but I don't know enough about them.
Well. I don't know how to write a dtd either, yet. But I should learn. I get the feeling that this would be a perfect wiki project. Since that would let people who know dtd and people who know the inx format tweak the document. But I'm not sure a wiki would handle that sort of character data. Perhaps it can find a home in CVS. If I should be XSchema let me know. This is what came up with from the *.inx files I have and no real knowledge of DTD:
Yes, go with XSchemas, don't bother with DTD's. They're supposedly deprecated, although a lot of people still use them. There's some docs on XML Schemas at xml.com.
IMHO, XSchemas aren't really that much better or easier than DTD's, but they're implemented as XML documents, so at least you're using a consistent syntax.

Just looking it seems to me that some elements might be missing (like input-extension). I also wonder if it would be worth the trouble to be consistent in the formatting of element names (ie replace all the _s with -s). But maybe there is a reason for the way it is.
Yeah, try to remain consistent. You've actually got three cases:
* dashed-words * underscored_words * joinedwords
I'd suggest going with just one style for all elements if you can.
