 >Is there an agreed validation mechanism for open-standards based on 
XML, i.e. do they only release a set of files which allow for validation 
(xml schema, relaxng) or do they release a tool which provides the 
validation when not all constraints can be captured using these languages?

I think practice is highly variable. Some open standards groups consider 
it enough to produce a prose specification, and leave all tooling 
questions entirely to implementors. Some consider it appropriate to 
supplement the prose specifications with things such as XML Schema or 
Relax NG definitions, which they will probably want to ensure are 
portable across multiple processors. Some consider it appropriate to 
provide an online validation service, which can be implemented using any 
tools you like.
