//  Contents:   Routines to enumerate (via a callback) the set of "default"
//              components that are installed under various conditions.
//
//  Notes:      We have default components and mandatory components.
//              Default components (which also include the mandatory
//              components) are installed during attended fresh installs.
//              Mandatory components are potentially installed during
//              upgrades to make sure that the basic (mandatory) networking
//              components are present.
//
//              Default components may also depend on on the suite or platform
//              currently running.  For example, WLBS is a default component
//              on the Enterprise suite, but not on normal Professional or
//              Server products.  Representing this flexibility is the main
//              reason a callback interface was chosen, instead of returning
//              static arrays of components.
//
//              Callers often need to know how many components will be
//              enumerated before they actually enumerate them.  To satisfy
//              this, the callback is first called with the count of items
//              to follow.  The callback routine therefore is passed a
//              message (EDC_INDICATE_COUNT or EDC_INDICATE_ENTRY) to indicate
//              the purpose of the call.
