XML schema validation accepting multiple schemas currently uses arrays
of Resource objects. They would be a bit easier and more succinct to
use if the setters were switched to varargs. Such a change would be
backwards compatible.
This change includes:
* change AbstractValidatingInterceptor#setSchemas to use varargs
* change the CommonsXsdSchemaCollection constructor to use varargs
* change CommonsXsdSchemaCollection.setXsds to use varargs
* update the tests to use varargs
