Simplification.  INCLUDE and IGNORE only occur in the DTD where you have
to do fairly heavyweight parsing anyhow.  CDATA sections can appear in
DTDless instances and are designed for lightweight parsing, thus no 
particular need for flexibility.  Also note that hardcoding INCLUDE or
IGNORE would be rare, you'd probably have a %peRef; of some sort, and
that expands with spaces around it, so the spaces have to be allowed. -Tim
