Scott and A. Soroka,
Thanks for the advice. Although a generic 'hasRelation' property would
suffice for now, it's certainly true that it would be problematic for the
future. Likely a custom namespace is in order for us - I'll take a look
at the UWDC example, and the Enchanced Content Models validation - they're
both going to be very useful.
Thank you!
Walker
