I've been consistently using 'name' to label things and 'from' to
refer to things that have been labeled.  Changing the 'name'
attribute to 'label' in all places would be consistent.  While
I prefer 'name' here, I'm not against using 'label'.

The 'label' attribute would be the the output?  Yes, I had
considered that and didn't rule it out.  I just made one
choice over the other.  I'd be OK with such an attribute.

Again, I'd like the choice of 'label' or 'name' attribute to
be consistent.  Here is a case for something more specific (e.g.
