| I'm curious. I don't see it in the XML spec, but are PUBLIC IDs
| really supposed to be in the form "-//Foo//Bar//Baz".
No, there's nothing about XML (or even SGML) public identifiers that
required that format.
| Is this an
| ISO format? If so, where is it defined?
Public identifiers in that format are known as "formal public
identifiers" and they are defined principally by ISO 8879
| The grammatical production "PubidLiteral" and its rules for space
| compression seem to encompass either a URI, the format above, and
| just about anything else you'd like to put in there.
Anything that uses only the pubid chars is fair game after normalizing
| Tool survey: IE5.5 won't display a file unless the PUBLIC ID is in
| the format above.
That's a bug.
| XML Spy doesn't care. Expat doesn't care.
| Xerces doesn't care.
No tool should care.
