/* Description: this provider manages the SLP advertisements for Pegasus.
   It gets information from other sources within the Pegasus environment
   (primarily the Interop Classes such as CIM_ObjectManager,
   CIM_ObjectManagerCommunicationMechanism, CIM_Namespaces, etc. and generates
   the corresponding registrations.
   It also maintains a single Class, PG_WBEMSlpTemplate that defines what is
   in the template.
   NOTE: This provider should NEVER be getting information itself but simply
   using other classes in the environment to generate information.
   The intrinistic operations that exist include:
   enumerateInstances
   enumerateInstanceNames
   getInstance

   This module provides an SLP service agent that is activited once the first
   registration is created.  This service agent provides either the normal
   SA functions or provides the registration to a DA if required.
   That set of functions in in the Pegasus service agent code.

   To initiate the SA within Pegasus, the system must make a first
   PEG_WBEMSLPTemplate enumerateInstances call to this provider or execute
   the register method.
   That initiates the build of the registration information and
   the startup of the SA.

   Note that this providers sets itself so that it cannot be removed
   once started.
*/

/*
    1. Currently SLP readvertisement happens in the following condtions.
        (a) When PG_ProviderProfileCapabilities instance is created or deleted.
        (b) When PG_Provider and PG_ProviderCapabilities instances are
            created.
        (c) When PG_Provider, PG_ProviderModule and PG_ProviderCapabilities
            instances are deleted.
        (d) When PG_ProviderModule is disabled or enabled.
    2. SLP advertisements for both EmbeddedSLP and External SLP will happen
       from this provider using slp_agent.
    TODO:
    3. Consider seriously the concept of instance creation where the instance
    is provided and that instance is registered as a profile.
    Not sure today what the level of validation, etc. would be required.
    4. We would like separate this function completely from the CIMOM so that
    the registration it could operate as first a separate process and second as
    a separte executable.
    5. Look at getting certain parameters as the default from the class.
    This way we could use the class definition for defaults.
    6. Determine if we really want to get enumerated  attribute strings from
    the class or from a string tied to the template.  If we get them from
    the class we are committed to whatever is in the class.
    However, in reality, the class and the template could be different
    in some cases.  For the moment we are getting them from the class
    and the template and class enumerations do match.
