Probably wants a Net prefix.

I don't think enum names typically have dots in them.

[nharper, 2015/12/04 01:42:20]

There are multiple enum names with dots in them - I modeled this after
DomainBoundCerts.Support.

If I'm changing the histogram name to have a 'Net.' prefix, should I change the
enum name as well?
