Re: Recursive replacement

This is in error as //a selects 2 nodes, and 
http://www.w3.org/TR/xqupdate/#id-replace
says:

   The target expression is evaluated. The result must be a single node
   whose parent property is not empty;  otherwise a dynamic error is raised

Hmm I'll leave that one for a WG member to answer.., I think that you
should get get an error from
http://www.w3.org/TR/xqupdate/#id-extensions-to-existing

  All the pending update lists generated by the previous step are merged
  by successive invocations of the upd:mergeUpdates operation. If the
  upd:mergeUpdates operation signals an incompatibility, a dynamic error
  is raised [err:TBD].  

But I don't actually see that in the table in
http://www.w3.org/TR/xqupdate/#id-compatibility
which has side condition "Not compatible if t1 is t2." in some cases
looks to me as if it should be t1 is an ancestor to t2
