hey dave, here's the blogger api expressed in an interface description language. (my xml-rpc server code uses the descriptions to figure out how to convert types on the way in and out, and dispatch the calls.) here's descriptions of the weblogs.com interface and the validation test suite. and the source code to use this last description to implement the server-side of the validation suite.

my plan is to someday use the same description files for generating client-side interfaces in php. but i haven't had a need to make any xml-rpc calls from php, so i haven't written the code yet.
