Fine by me.

Recall that elements may have attributes defined as globalWithType (has 
attributes type and subtype, both as xs:string). Would your proposal 
require both to have the "x-" prefix for all values?

Attributes are also defined in globalWithoutType, which allows an 
element to have a defined type but it also has a subtype with xs:string. 
Same question for the subtype attribute here?

Already have the simpleType "attributeExtension" so we can just set the 
type/subtype attribute type to that. If later define a type of an 
element, just union the enumeration with "attributeExtension."

Fairly clean and requires minimal changes.

Comments, suggestions?
