But if my understanding of SSML spec is correct, without change to
schema SSML documents with foreign elements/attributes will be always
non-conforming, becuse in sections 2.2.2.1 and 2.2.2.2 validity against
schema is one of conformance criterias. And if schema doesn't permit
foreign elements/attributes, then such document will be invalid, and
thus non-conforming. However, I'm not sure if this is true intent of
specification.

Maybe, if you do not want to change schema, you can say that foreign
elements/attributes are stripped from conforming SSML document before
validation.
