xml-dev - ATTLIST question

[James Gray <jmgii@yahoo.com>]

Greetings:

I'm trying to create a DTD that will incorporate an 
attribute list that will allow  the following case:


  1. Define optional values for an element
  2. Require one of the options be present
  3. Not allow any option other than those listed

I've scoured my XML books and can't figure out how
to implement such a case.  An example that is 
similar is for shirts.  I'd like to have a "shirt"
element that is only allowed to the values:
S, M, LG, XL

If the <shirt> element is filled with "XS" or "XXL",
I would be able to reject it based on my DTD?

Not impossible, right?

Thanks in advance for responses....

James
