Major Description
Hi
the geronimo schemas are not valid. This patch resolves this issue and adds a corresponding test to the core module.
Most problems arise from namespace errors and are now corrected.
The TestCase (GrammarTest) just reads the grammar files and validates them internally. A simple EntityResolver is included in the test which searches all grammars needed in the schema directory of the core module (for example: datatypes.dtd, XMLSchema.dtd,...). So the test doesn't need a remote connection for these dtds.
The geronimo-web-app.xsd file is not included in this patch and is still invalid. IMHO this should be resolved as soon as possible.
