Further to discussion some time back, here's a catalog for all the TEI
external entities, which works for me with sgmls and a suitably
modified set of tei*.{dtd,ent} -- patches or a perl script to do this on
request.
 
Note this catalog needs to be placed in a directory WITH all the tei
p3 files, and then sgmls invoked as
 
sgmls -m <teidir>/catalog <teidir>/sgmldecl.tei ...

[Maybe THIS will encourage Lou and Michael to do it themselves! :-]
