xs:union alternative

Hi,
 
I am seeking any alternative to replace xs:union. Suppose I have an
element which
allow the following contents - "UTF-8", "GB2312" & any String.
 
Normally, I can create 2 simpleTypes (one for "any String" and one for
pre-defined
values) and using xs:union. Is there any alternative that I can define 1
simpleType to
solve the problem.
 
Regards,
 
Tony
