The TEI1.dtd file says:
 
<!ENTITY  % ISOLat1       PUBLIC
            "ISO 8879-1986//ENTITIES Added Latin 1//EN"         >
<!ENTITY  % ISOLat2       PUBLIC
            "ISO 8879-1986//ENTITIES Added Latin 2//EN"         >
 
but when I run SGMLS over this, I get the following:
 
curia% sgmls SGML.dec curia.dtd teih oengus.html
sgmls: Error at /tlh/curia/dtds/TEI1.dtd, line 42 in declaration parameter 5:
       Could not find external parameter entity "ISOLat1"
sgmls: Error at /tlh/curia/dtds/TEI1.dtd, line 44 in declaration parameter 5:
       Could not find external parameter entity "ISOLat2"
 
I *do* have the required files:
 
curia% ls -l ISOL*
-rw-r--r--  1 pflynn       4296 Dec  1 15:56 ISOLat1
-rw-r--r--  1 pflynn       7389 Dec  1 15:57 ISOLat2
curia%
 
but SGMLS is probably looking for them in some other directory, at a guess.
Has anyone any clue as to where it's looking for them (or if it's looking for
some other filename than `ISOLat1' or `ISOLat2')?
