## Detailed Description

FdoPhysicalSchemaMapping is an abstract class that is the base class of all Schema Override sets. Each instance contains the overrides for a particular Feature Schema and FDO Provider. Each FDO Provider, that allows Schema Overrides, must create a sub-class of this class. This sub-class must implement the overrides that are specific to the provider. The Provider can also add support, for serializing to an XML document, by overriding the functions inherited from FdoXmlSerializable.
