Yeah, it's nice that you don't have to subtract
FirstLowInvalidHeapAttributeNumber in so many places. I think future
changes might end up using attidx when they ought to use attrnum (and vice
versa), but you could just as easily forget to subtract
FirstLowInvalidHeapAttributeNumber today, so it's probably fine.

nitpick: Shouldn't this be an AttrNumber?

These all looked reasonable to me.
