The issue Simon is exercised about is user-defined XPointer scheme
names.  The XPointer Framework PR spec. [1] mandates the use of QNames
with prefixes (pf:sname) for non-W3C scheme names.

The logic of this decision is as follows:  

  1) schemes are going to be popular (Simon himself has already
     defined several);
  2) short scheme names are likely to collide;
  3) collision is an interop nightmare;
  4) scheme names therefore need to incorporate domain names in some way;
  5) we'll reuse the nsdecl/nsprefix design pattern.

Constructive discussion on where the above logic falls down and/or how
the above goals can be met in other ways will be welcome, here and/or
to www-xml-linking-comments@w3.org.
