support for required attribute name aliases and/or attribute/attributeGroup
choice

In 1.1 you can achieve element name aliases:
 - substitution groups
 - <xs:choice>
But none of this works on attributes where you want required attribute name to
have an alias:
 <ELEMENT name="Some Element">
 <ELEMENT caption="Some Element">
where "name" or "caption" should be specified. Another case is when you want to
have alternative attributeGroups for an element with required ones included. 

Motivation:
In my opinion this may by non rare case when you create schema for existing
inconsistent XML documents ensuring backward compatibility or other motivations
that bring substitution groups to elements. Anyway in my opinion similar
capabilities should be available for elements and attributes.
