In Schema 1.0 it's only possible if the two elements have different types,
and that's only possible if they appear in different contexts.
 
In Schema 1.1 this is easily done using conditional type assignment.

Subject: multiple attribute groups for an elment possible?



Hi all,



I'm trying to figure if it's possible to have essentially several valid
attribute groups per element.  For instance, if I have two types of symbols,



<symbol type="a" a="val" b="val" c=123 />

<symbol type="b" x="val" y="val" z=123 />



I would like to say that type "a" has these required/optional attributes,
i.e. a, b, and c, and type "b" a different set, i.e. x, y, and z.  Is it
possible to say that "symbol" can have one of several attributeGroups?



I realize I can just make aSymbol and bSymbol but would like to avoid that
route.



Cheers,

Zach
