Re: Schema.org External Enumerations mechanism

Looks good to me.

"""
Each such URL has the following structure: 'http://schema.org/' + 'ext/' +
authority id + '/' + scope + '/' + term
"""

Is that in conflict with the proposal elsewhere (
http://ext.schema.org/wikipedia etc.), or am I misunderstanding? If it's
not in conflict could you add an explanation?
