I'm not quite sure exactly what you mean by "I'd like people to be able to
redefine certain types into enumerated lists", but possibly what you need to
do is define a simpleType with your enumerations as you suggest. Then add
the attribute by extending the simpleType into complexType, simpleContent.
<xs:attribute name="MyAttribute" type="???????"/>
P.S. Thanks to all those that answered my questions earlier today.
