/**
* Object model meta factory.
* This interface encapsulates a particular object model and provides instances
* for plain XML, SOAP 1.1 and SOAP 1.2 object model factories for the
* given object model implementation. Currently the two OM implementations provided by
* Axiom are LLOM (linked list) and DOM.
*
* The factories returned by {@link #getOMFactory()}, {@link #getSOAP11Factory()} and
* {@link #getSOAP12Factory()} might be stateless (and thread safe) or not. In the former
* case the implementation should return the same instance on every invocation, i.e.
* instantiate the factory for each OM type only once. In the latter case, the implementation
* must return a new instance on every invocation. In order to work with any OM implementation,
* code using an implementation of this class must call the relevant method once and only once
* for every document processed.
