A namespace is usually simply a URI to make sure it is globally unique, 
in this case
   http://www.w3.org/TR/2001/REC-xmlschema-1-20010502/#element-schema
targetNamespace is defined to be of type anyURI and that is defined here:
http://www.w3.org/TR/2001/REC-xmlschema-2-20010502/datatypes.html#anyURI
