Adam:
(Agreeing with Pete.)

Part of the problem is that XML can be used for many different purposes,
and my experience is that various graphical models can be helpful in
various circumstances.

For instance, ERDs are quite useful if your basic application structure
is based on a relational database, and you're using XML to move that
data around.  OTOH UML diagrams can be useful (like those in newer
versions of XML Spy) for object serialization scenarios or for modeling
document relationships.  Stylus Studio and oXygen are nice tools as well
with their own ways of representing things.

As far as I can tell, no one has yet invented a perfect tool/language in
which to model the whole of XML.  If you find one (and I'm sure there
will be one at some point) please let me know!  For now, I'm afraid you
have to choose one that best fits the needs of your application.

Best regards,
David Ezell

Pete,

I was looking for a graphical diagramming method.

I understand what you're saying. Thanks none the less!

Are you looking for things like XML Schema, Relax-NG, Schematron and so
on? 
Or are you looking for graphical methods?

If the latter, I'm not aware of any formal methods, but a number of
tools do represent schemas using graphical methods. However, in my
experience, in most cases the graphical representations only capture a
fraction of the information you need, and while sufficient for a screen
based representation with which you can click to get more information,
they probably don't translate well into paper based representations.

HTH,

Pete.

All,

Is there a popular notation for modeling a vocabulary? I'm accustom to
ERD's for database data modeling. I tend to use that for data modeling
XML vocabularies, but I want to know if there is a better way to do
this.
