These seem to be gone now, but isn’t it common to document the enum values? I know we do that in several places in LLVM. 

Thinking about other cases, it probably also worth having an “enum class”, an enum within a class, and one in a namespace.  I’d suggest also varying in at least one case where the doc comments are: e.g., above the value vs on the same line.
