Standardized Apache DTD

Hello Everyone,

We are in the middle of a project to build an OpenSource XML based ,
administration tool for Apache. I've seen  early posts discussing
possible approaches but nothing to indicate a consensus. We'd hate to
re-invent the wheel if a DTD has already been established.  Does anyone
know if there is a project underway addressing a standardized DTD for
Apache Administration and it's status? Are there others interested in
collaborating on an effort such as this?

Thanks for your help in advance,
Chris
