XPP editorial tweaks

Hi folks,

I asked Paul to look over the XPP status and he made a few comments
that I've implemented:

* Editorial changes in the SotD.
* Combined normative/informative references into just references.
* Removed the conformance section.

                                        Be seeing you,
                                          norm
