/****h* OpenSM/Inform Record
* NAME

* DESCRIPTION
*	The Inform record encapsulates the information needed by the

*
*	The inform records is not thread safe, thus callers must provide
*	serialization.
*
*	This object should be treated as opaque and should be
*	manipulated only through the provided functions.
