Jakob,
I have to agree with Marcus, that attributes of that length are in the least unusual. Still, exceeding a quantity should result in invalid SGML, but not truncate the export. I therefore suspect you are bumping up against an implementation dependency of some sort.
  The relevant quantities are:

ATTSPLEN (normalized length of a start-tag's attribute specification list)
LITLEN (which applies to the length of an attribute value after entity and character references within it are interpreted)
NORMSEP (used to separate values in a list-valued attribute)
TAGLEN (length of a start-tag)

The Dev Guide says that ATTSPLEN, LITLEN, and TAGLEN can be increased up to 30 times their values in the reference concrete syntax (respectively, 960, 240, and 960).

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.
