Frameworks DTD files

I hope this doesn't come across as a moan as its meant to be more of a general question to the community. But with all the main frameworks out there running on XML config files, where are the official DTD's hosted for these? I know there are several around hosted in odd locations (no disrespect), but I was just looking to put together a definitive list of the locations. I know you can get them via subversion etc but shouldn't/couldn't they be hosted on the respective sites??
