The number of users who trip over this, looking 
for a context change to change the definition of the axis;
e.g.
  <for-each>
   <sort>
     ..look for unique / first of its kind etc.

Is this one for XSLT 2.0 ?
  Either saxon:distinct, or something which will allow us
to work in the node-set that we have created in the new context.

 I'll look to others for suggestions, but I think the principle
is valid, especially with its frequency of use.
