There are three cases, in general:

- "flawed" -> reject request with 4xx error

- "don't understand any" -> ignore (and maybe special-case route it to 
some smart entity that might) or generate error

- "don't understand one of the schemes" -> ignore and pick one you 
understand

I'm assuming a model where a request may contain multiple location 
references, just like LoST responses can point to multiple PSAP URI schemes.

That, by the way, is the level of detail that the draft might want to 
have and seems to be leaving somewhat under-defined.
