There was some discussion of this in the previous email thread (please ignore the discussion in that thread of what became issue #277, the stuff about registering multiple resources at once, which we discussed today). We're specifically talking about the uri field in the resource description doc here.

As it happens, Gluu has found it useful to be an array, and already implemented it this way through need. And Mike is bringing up the notion of allowing wildcards that would have meaning, though he acknowledges the semantic complexity this brings. In the thread, James questions the use cases for this.

I'm not presenting a list of options for this one -- have at it. :-)
