Re: empty elements and xsd:string

Hi Bryan,

That is an empty string. For instance the XML Schema specification part 
2 contains an example that defines a non empty string so it is clear 
that the empty string is accepted by xs:string.

http://www.w3.org/TR/xmlschema-2/
4 Datatype components
4.3 Constraining Facets
4.3.2 minLength
http://www.w3.org/TR/xmlschema-2/#rf-minLength

Example
The following is the definition of a ·user-derived· datatype which 
requires strings to have at least one character (i.e., the empty string 
is not in the ·value space· of this datatype).

<simpleType name='non-empty-string'>
   <restriction base='string'>
     <minLength value='1'/>
   </restriction>
</simpleType>

Best Regards,
George
