Detailed Description

Tri state Capability match result.

CapMatch::irrelevant denotes a result value that should be ignored. Therfore it behaves neutral when used in ! && || expressions.

   CapMatch any
   (CapMatch::irrelevant && any) == any                  // true
   (CapMatch::irrelevant || any) == any                  // true
   ( !CapMatch::irrelevant )     == CapMatch::irrelevant // true
