OK, is the option open to us of deciding that the Namespaces spec, by 
"character-for-character", really meant that the latter of the two above 
must always be treated as equal, and furthermore equal to the first 
because in this case the hex-escaped char 'L' is in the "safe" set?

Second question, if we could do this, should we?  I.e. do people feel 
that these really are effectively always the same URI in all possible 
sets of circumstances?  Seems that way to me.  -Tim
