True, and arguably normalize-space doesn't go far enough either (though
enough for XPath only). The basic distinction between CDATA and the other
declared value types has to do with (white-space delimited) tokenization.
XML 1.0 missed the boat here, in that tokenization still needs information
from the DTD. We might have dedicated the LITA delimiters (single quotes)
for this as a purely syntactic distinction, for instance.
