/**
 * Resin's implementation of the JNDI DirContext.
 * The actual storage
 * of the persistent data is in the AbstractModel.
 *
 * The DirContextImpl is just a Visitor around
 * the AbstractModel which also encapsulate
 * the JNDI environment.
 *
 * 
In JNDI, each Context is a <model, env> pair.
 * Each client might pass a different environment
 * to the InitialContext so each ContextImpl
 * must be unique for each client.  (Granted, this is a bit wasteful of
 * space which is why JNDI values should be cached.)
 *
 * Applications which want a different model can still use
 * ContextImpl and specify the root
 * object for AbstractModel.  ContextImpl will
 * take care of the JNDI API for the model.
