In general, the lexical space tells you the actual character strings that 
can be present in an XML document (or other context) to represent a value; 
 the value space tells you the set of abstract values that comprise a 
given type.  For many types, such as the numeric types, the differences 
are clear, but there is no reason why a particular type cannot have a 
straight 1-to-1 correspondence between characters in a lexical space, and 
a value space that happens to consist of the same character sequences. 
Obviously, if all types were this way, the architectural distinction 
wouldn't likely be made.
