I would have thought that the following from the Configuration
Guide would allow for a DynamicSchemaProcessor with no
Catalog or CatalogContent:

If the CatalogContent is specified, then it is used as the schema 
definition content. If, in fact, it is specified, then the value of 
DynamicSchemaProcessor, if any, is ignored.

Finally, the DynamicSchemaProcessor connection string property is the 
class name of a class that implements the DynamicSchemaProcessor 
interface. If set, an instance of the class is created for each schema 
request and its "processSchema" method is called which returns the 
schema definition content.
