I have succeeded in getting P3 to compile using mkrls 2.1 rel 1.25 by dint
of manually including the relevant files in one monolithic tei2.dtd (thanks
for the pointers, Lou :-)
The files tei2.dtd, tei2.rls (Sun) and a slightly bodged sgmldecl.tei are
available for anonymous ftp from curia.ucc.ie in pub/sgml (the bodge to the
SGML declaration was to increase GRPCNT and make SUBDOC NO.
