gml

[Yasushi Shoji <yashi@xxxxxxxxx>]

hi all,

while i'm installing jade and dsssl, i tried test.sgm with nsgmls
$ nsgmls -sv test.sgm
and i get following error

nsgmls:./docbook.cat:30:0:W: DTDDECL catalog entries are not supported
nsgmls:./docbook.dtd:119:0:E: cannot open "./iso-amsa.gml" (No such file or directory)
nsgmls:./docbook.dtd:126:0:E: cannot open "./iso-amsb.gml" (No such file or directory)
nsgmls:./docbook.dtd:133:0:E: cannot open "./iso-amsc.gml" (No such file or directory)
nsgmls:./docbook.dtd:140:0:E: cannot open "./iso-amsn.gml" (No such file or directory)
.....


first line is ok, since i know the DTDDECL is not supported by jade package.
after second line, it says that it can't find *.gml.
where can i get .gml files?
what package do .gml files come with?
what are they?

thanx in advance

regards,
