hallo everyone

my knowledge of xml is advanced, but not concerning namespaces.


i've got the following error when validating the xml instance document =
against its schema.

i think it's got to do with the namespaces...


thank you for your time and effort
greetings elly


ps: im using altova xmlSpy, enterprise edition 2005 rel. 3
