… still working on this …

Am I correct to believe that *some* placeholders even in client ≥ 1.4 will only 
support (and therefore require) 2 fields, and therefore in those particular 
cases

        $<field_1::field_2>$

can, and would, be valid? Or effective with ≥ 1.4, must a second pair of colons 
::  always in every case be specified, thus

        $<field_1::field_2::>$
