Can you tell us the name of the object and the property, and describe the different contexts? I'm having trouble imagining such a requirement.

It seems to me a property that can return multiple values isn't really a property. It's either a method you pass a parameter to (to specify "context" -- which of course won't work for bindings), or it's multiple properties (i.e., multiple selectors -- what's not clean about that?).
