The Core WG reviewed this issue once again and stands by their
earlier resolution.

From the minutes[1] of the 26 Jan telcon:

normalization

We want xml:id values to be normalized in the infoset.
Ian says browsers don't now do this; he doesn't like
the fact that we are changing the infoset values for
xml:id from what they would be in an infoset created
by an xml:id unaware processor.

But we are quite sure we do want to do this for xml:id.  
Given that we are changing the type of xml:id from CDATA 
to ID, it doesn't seem additionally problematic to normalize
its value too.  It won't break existing documents, since 
there can be no existing documents that use xml:id.  
Our proposed behavior is equivalent to putting something
in your internal subset declaring xml:id to be an id.

                                        Be seeing you,
                                          norm
