No.

Namespace specifications define the namespace-specific part; nothing 
else. Fragment syntax and semantics are defined by RFC 3986.

A spec *can* point out that the URN does not identify something from 
which a payload + media type can be retrieved, in which fragment 
identifiers are not applicable. But that's different from disallowing them.
