/**
 * A parser for "embedded" endpoints - ie inbound, outbound and response endpoints.
 * Because we have automatic String -> MuleEnpointURI conversion via property editors
 * this can be used in a variety of ways.  It should work directly with a simple String
 * address attribute or, in combination with a child element (handled by
 * {@link ChildAddressDefinitionParser},
 * or embedded in
 * {@link AddressedEndpointDefinitionParser}
 * for a more compact single-element approach.
 *
 * <p>This class does support references to other endpoints.</p>
 * TODO - check that references are global!
