I would offer choosing to either have a bunch of protocol data elements conveying what capabilities need to be conveyed, a parameterized string, or a structured string. I would offer that creating PDE's makes extensions problematic and structured strings are doomed to interoperability failure. That leaves a string with (extendable) parameters.
