org.geotools.xml.schema.Schema

This Interface is intended to represent the public portion of an XML Schema. By public portion, I mean the portion of the Schema which can be included in an instance document, or imported into another Schema.

The distinction between the public portion of a XML Schema and the entire XML Schema is or particular important when comparing, or printing two XML Schemas. This interface does is intended to provide enough information to re-create the original Schema (note the lack or annotations as an example). This interface is however intended to provide functional semantic equivalence. By this is mean that two XML Schemas represented using this interface should have the same SET of declarations. There is no guarantee that the Schema represented matches the original document with respect to orderwithin the sets, except where order is explicitly defined (Sequence, Choice).

This method must be inplemented within extensions: public static Schema getInstance();. It will be used by the Schema factory to load the required extensions into memory.
