I'm not sure what you mean by "getting" enumeration values.  If you want 
to do something like extract them from the schema itself, well schema 
documents are themselves XML documents, so you could run a stylesheet over 
your schema document.  Are you looking for something like:

        <element name="container">
         <sequence>
                <element ref="e" type="someEnumeration" maxOccurs="*"/>
         </sequence>
        </element
 

and to insist that the values of e occur alphabetically.  The answer in 
Schema 1.0 is no, can't do it.  In schema 1.1, the new "Assertions" 
facility would let you put an XPath assertion on the container.  If your 
processor supported a sufficiently broad subset of the XPath language, and 
if your definition of "alphatbetical order" involves a string comparision 
that XPath can easily do, then yes, I think you could enforce that in XML 
Schema 1.1.
