Almost.  CDATA section processing happens during construction of the input
info set.

Yes, CDATA sections are allowed in _element content_ that is declared to be
of type xsd:string (you can't have CDATA sections in attribute values).
However, within a CDATA you do NOT need to escape < and & (that's what the
CDATA section does).

No offense, but it wasn't schema that has inappropriately named something:
XML uses the term CDATA in two different contexts...
