I think so. There seems to be an unarchitected mechanism [1] to extend
the field length but the spec says its use is discouraged.

[1] MO:DCA spec, Eighth Edition, "Structured Field Syntax", SFI
semantics, Bytes 6-7, page 21/22.

If the truncated part is not just whitespace, then yes, IMO.

org.apache.fop.afp.modca.TagLogicalElement, line 128.
Simply check if the value is longer than allowed and then check if the
truncated part contains anything other than spaces.
