15    //  Summary:
16    //  A semantic action policy holder. This holder stores a reference to ref
17    //  , a const reference to value1_ref and a const reference to value2_ref.
18    //  Typically, value1_ref is a key and value2_ref is value for associative
19    //  container operations.
20    //  act methods are feed with ref, value1_ref, value2_ref. The parse result
21    //  is not used by this holder.
22    //
23    //  (This doc uses convention available in actors.hpp)
24    //
25    //  Constructor:
26    //      ...(
27    //          T& ref_,
28    //          Value1T const& value1_ref_,
29    //          Value2T const& value2_ref_ );
30    //      where ref_, value1_ref and value2_ref_ are stored in the holder.
31    //
32    //  Action calls:
33    //      act(ref, value1_ref, value2_ref);
34    //
35    //  () operators: both
36    //
