Use IsTypeSupported, since it is the permanent name for this functionality.

Done.

should we just call this "properties" to support other options? Going further,
maybe this should be a vector of pairs of strings. Of course, YAGNI, this is
simpler, and we can always change it.

Yeah, added a TODO for the possible future refactoring.

[ddorwin, 2013/08/28 02:28:50]

I'd just drop the TODO since we don't plan to address it unless/until needed. We
recognize and accept the current limitation, and the solution will hopefully be
obvious when the time comes.
