Re: Invalid character found [dtd]

Mike --

The beauty of XML is that it is (relatively) easy to write software
to process it. The way this was achieved is to limit the variations
in the syntax and to (virtually) prohibit users from making syntax
changes.

/ isn't a legal XML name character, and there's nothing you can do
to make it one.  (You could do your EAD processing in SGML, where
you could make this change, but if you do you won't be able to
use all the cool new XML tools.

I suggest making up a different code for "box/folder". Perhaps
"BoxInFolder" or "BoxOrFolder" or something else that describes what
you mean within the limits of XML names.

Friends,
I am writing a stylesheet for EAD 2002 XML tag set (into PDF). I am
writing it against the DTD. I wanted to make the DTD more exact. The
problem I have is that the syntax in the ATTLIST has an illegal
character "/". Anyone have any idea how I can change the DTD so that
it will accept the "/" character as an attribute value?

Examples below.

Thanks,
