Note that this is only well-formed in the
external document type definition subset.
Er, in english, this means that you can't use parameter entities in this
way in the main document file, but only if the DTD is in an external fil.
If you want to be able to define and/oruse the entity anywhere, do it
like this instead:
<!ENTITY % docAtts
title CDATA #IMPLIED
header CDATA #IMPLIED
footer CDATA #IMPLIED
It is legal for there to be multuple attribute list declarations for
the same element type, by the way.
