Yebbut... why? I've never seen an attribute value that size. If I had a
value that big, I'd be looking for some further breakdown of it. Are you
sure that big a chunk is necessary to assist in the description of the
element?

Some things can be changed in the SGML Declaration but the change won't be
reflected in FrameMaker. I would have thought that LITLEN would be the one
to change.
