Discussion:
The usual pattern now used for identifying where bitmask elements are declared, namely, as variables, preclude declaring them as enumerators.
Compare:ctype_base::space in C++03 subclause 22.2.1 [lib.category.ctype] versus the same in N4582 subclause 22.4.1 [category.ctype]. It is unclear whether this is intentional. Further it is unclear if odr-use of bitmask elements is intended to be allowed.

Jonathan believes that this was intentional, and was done by N3110. Jonathan will provide more precise references.
