We have recorded this issue at [1]
wherein our resolution is listed as follows:

  Resolution: Noted. The Core WG doesn't see any reason why the XSL WG 
  would need to define XML 1.1 result trees, so the only issue is 
  serialization of 1.1, and algorithms for doing that in the presence
  of sensible data are well-defined. A note will be added to XML 1.1
  about how to serialize 1.1 documents (given normalization).


The above mentioned note in our latest draft at [2] is:

  XML applications that create XML 1.1 output from either XML 1.1 or
  XML 1.0 input should ensure that the output is fully normalized; it
  is not necessary for internal processing forms to be fully normalized. 

Please let us know if you are not satisfied with this resolution of
your comments.
