The latter, IMHO.  One reason is that PS and LS are meant for plain text
formatting.  They can be used to "pretty-print" XML source just like CR and
LF in their various combinations are.  As John Cowan just pointed out, XML
1.1 folds PS into an LF to effect that.  Giving markup meaning to PS and LS
would in a sense override their plain text meaning.

Another reason (unrelated to NOTE-unicode-xml) is that they are not
containers like elements but just delimiters.  Unlike some other Unicode
formatting characters like the bidi ones, they cannot unambiguously be used
to indicate containment.
