Re: [xml-dev] Extending Types in xml schema

I think the OP was trying to extend a type comprising a repeating choice by
adding another branch to that choice.  The base type was (a|b|c)* and he
wanted the derived type to be (a|b|c|d)*.

I'm only interpreting for him because I'm curious about the answer to that
question.
