He quoted it already: http://www.w3.org/TR/xml/#AVNormalize

But later addmitte an error with regard to collapsing of spaces:

- Comment #10 From Henri Sivonen 2010-06-22 06:28:04 (-) [reply] -------
Oops. Sorry. Collapsing consecutive U+0020 characters applies only to non-CDATA
attributes.

So I and Henri agree that http://www.w3.org/TR/xml/#AVNormalize require XHTML
parseres to normalize tabs, line feeds and carriage into space characters,
within CDATA attributes.
