* Head of this profile's list of endpoints. This endpoint is not

* one endpoint.
*
* Currently, a profile contains more than one endpoint, i.e.,
* list contains more than just the head, only for two cases
* (1) when RTCORBA is enabled and
* (2) the ORB is initialized with -ORBPreferredInterfaces option.
* However, in the near future, this will be used in for mode as
* well, e.g., to support TAG_ALTERNATE_IIOP_ADDRESS feature.
*
* This is probably as good a place to discuss how the list of
* endpoints is used for #2. If the ORB is configured to use
* preferred interfaces for invocation, TAO creates an endpoint per
* preferred interface. To be clear, every tuple
* <destination:target> will have an endpoint. What TAO essentially
* does is that creates it multiple endpoints so that the invocation
* code path can use existing iterating techniques to try one
* preferred interface after another (if the first did not work). If
* the ORB is configured with -ORBEnforcePreferredInterface set to
* false in addition to the ORBPreferredInterfaces option , TAO
* creates another endpoint with the preferred bit set to null, so
* that the invocation code can fall back to a SCTP stack returned
* local address.
* Addressing info of the default endpoint, i.e., head of the list,
* is transmitted using standard SCIOP ProfileBody components. See
* <encode_endpoints> method documentation above for how the rest of
* the endpoint list is transmitted.
