>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.
