Yes, the serialisation type, but also you mention possibly representing different coordinate reference systems. These are exactly the types of things OGC moves to a "Capabilities" document, which is one of the operations available on every OGC service. It always includes things like CRSes, output formats, and query capabilities. 

How about this idea. There's a link/href at the POIS level that points to this kind of capabilities information. This is much the same pattern as Atom Publishing Protocol too.
