This interface specifies how the parser and the application interact with respect to Grammar objects that the application possesses--either by having precompiled them or by having stored them from a previous validation of an instance document. It makes no assumptions about the kind of Grammar involved, or about how the application's storage mechanism works.

The interaction works as follows:
- When a validator considers a document, it is expected to request grammars of the type it can handle from this object using the retrieveInitialGrammarSet method.
- If it requires a grammar not in this set, it will request it from this Object using the retrieveGrammar method.
- After successfully validating an instance, the validator should make any new grammars it has compiled available to this object using the cacheGrammars method; for ease of implementation it may make other Grammars it holds references to as well (i.e., it may return some grammars that were retrieved from the GrammarPool in earlier operations).
