2. Issue Definition
Literal/expression assignment semantics is not clearly defined. For example, are the following legal?
<variable name="intTypeVar" type="xsd:int"/>
<variable name="intElemVar" element="somens:intElem"/>
<!-- intElem is of type xsd:int -->
AS1: <from>0</from> <to variable="intTypeVar"/>
AS2:<from><somens:intElem>0</somens:intElem></from> <to variable="intElemVar"/>
Note: The current schema prohibits this.
