This is available on Core MIDI 1.5 and laters.
Can we have a fallback to use kMIDIPropertyName for the case this query fails?

I'm finding a document which Core MIDI version is used in each OS X, but could

Mac OS X 10.6 or later is supporting OS X versions.

If 10.6 supports Core MIDI 1.5, we do not need the fallback.
