Parameter entities are simply a short-hand, local to a DTD.  Thus
TITLETYP is simply a short-hand for the string "( AT | OT)".  Therefore
the content model for WORKTITLE is actually:

<!ELEMENT WORKTITLE (TITLE+, LNGCDE?, (( AT | OT))+)>

after the DTD has been parsed.  TITLETYP is not declared as an allowed
element type - hence the error.  (Note also that you have a redundant
pair of brackets around "AT | OT".)
