Namespace problem

Hello,

when validating (strict) the included XML-document versus the included 
schema i get following error (its the only error):

Invalid per cvc-complex-type.1.2.4:
   element {grips://xml.recom-verlag.de/comm/plem}:fallImportExport not 
allowed here (1) in element 
{grips://xml.recom-verlag.de/comm/plem}:fallInterface, expecting 
[{None}:fallImportExport]:

I think by setting the targetNamespace in the schema, the elements and 
types are in the namespace "grips://xml.recom-verlag.de/comm/plem", so 
why is the namespace 'None' expected (and whats the meaning of the 
[]-brackets)?

Thanks

Volker Zink
