I had always understood that CLASS was broken in some sense in that the
standard RR types ignored it.  I did not realize it had been designed as
a NULL .

Can it be ignored as long as it is part of the syntax?  Or does it need
a footnote in any definition?

Also,
Is the definition of names in this only related to DNS usage?

When looking at URL syntax is  it safe to say that the domain names only
refer to  hosts within the set of Common Internet Schemes?  And that
names in other schemes are outside these definitions are thus not
Internet domain names (though of course they can use same syntax if they
wish).

Or am I making some sort of category error?
