I recommend that folks use public ID's ala:
"-//IETF//DTD HTML ..."
only for DTDs standardized (or in the standardization process)
by the IETF. I suppose HTML 3.0 falls in that category, but...
You're safer not to presume that IETF is the owner of a DTD.
I'm maintaining a catalog of W3C DTD's at:
http://www.w3.org/pub/WWW/MarkUp/html-test/catalog
-- Ways to refer to Level 3: most general to most specific --
PUBLIC "-//W3C//DTD HTML//EN" html.dtd
PUBLIC "-//W3C//DTD HTML 3 1995-03-24//EN" ../html3/html3.dtd
Note that html-test/html.dtd is quite often broken -- it's the DTD
I edit for experimental purposes.
Better yet: use a URL as a system identifier:
<!doctype html system
"http://www.w3.org/pub/WWW/MarkUp/html3/html3.dtd">
or use both a public identifier and a system identifier:
<!doctype html public "-//W3C//DTD HTML 3 1995-03-24//EN"
"http://www.w3.org/pub/WWW/MarkUp/html3/html3.dtd">
Note that nsgmls supports http: urls as system identifiers, and
it will go over the web and get the DTD!
