Should add ttp:profileCombination with values "replace" or "mostRestrictive", with default "replace". The current definition in 1.0 is effectively "replace", but an author may prefer that the most restrictive definition holds. Perhaps also a "leastRestrict" value is in order as well.
Add notes (no markup allowed, URIs get automatically hyperlinked):
It would be useful to have background on the use case that motivated this solution.
[glenn]: this issue relates to the language in 5.2 related to combining multiple profiles
[glenn]: need to distinguish whether this is related to semantics of processor or content profile
EBU liaison has requested feature to allow document conformance to (zero to many) profiles to be described using short form aliases to allow references to specifications not wholly defined by schemas or feature designators, i.e. where behaviour is described normatively in documentation.
[pal]: Add ttp:profileCombination parameter
