//              the exception stack in the absence of an END_CONSTRUCTION
//              macro at the end of the constructor.

//  Synopsis:   Checks if the index <-> wid pid association is fresh.

//
//  Arguments:  [iid] -- index id
//              [wid] -- work id
//
//  Returns:    Shadow if (wid) most recent index is iid
//                   or Master if (wid) not found (meaning: master index)
//              Invalid if (wid) has a more recent iid

//  Notes:      When the document is deleted, the entry
//              will contain iidDeleted, wich does not
//              match any valid index id.
