The non-normative part of the Namespace rec seems to agree with you [1] (The "title" refered to here is an attribute): "...In this example, there are three occurrences of the name title within markup, and the name alone clearly provides insufficient information to allow correct processing by a software module." The implication of this sentence is that the type and the identifier should have a 1-1 mapping. I think it is pretty clear that the syntactic sugar of the Namespace rec doesn't handle hierarchies all that well, and that Per-Element-Type partitions introduce such hierarchies (of at least one level anyway). So I feel that the options are (a) enhance the syntax or (b) simplify (i.e. flatten) the interpretation of what namespaces are. The current situation is just confusing. Option (b) implies that an identifier might map to multiple types. I think the question boils down whether this ok or not.
