SV: empty elements and xsd:string

Okay thanks George,

But I'm wondering now, does this mean that there are also empty
nonNegativeIntegers and the like?

Best Regards,
Bryan Rasmussen

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 ˇuser-derivedˇ datatype which 
requires strings to have at least one character (i.e., the empty string 
is not in the ˇvalue spaceˇ of this datatype).

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

Best Regards,
George
