That's already in the spec in a few places, but I don't know if we say 
it categorically about all components.

For example, isn't it possible to have two Message Reference components 
with the same names but different properties? Also, would such a 
requirement be across the context of all existent components, just 
those in a single document, a single component model, etc?
