Castor can't unmarshall FilterComponent

[darmbrust]

Castor has some sort of bug which causes it to be confused by the structure of FilterComponent.

This XML, which is schema valid (and is in fact, generated by castor) will cause castor to choke upon unmarshall:

A workaround for this problem has been added to the cts2-model.pom file - which simply modifies the generated FilterComponentDescriptor to disable the validation in castor that is currently broken.
