How about this:
New syntax Expanded syntax
Extension of
---------------------------------------------------------------------------=
-----------------------------
pkg[foo?bar] foo? ( cat/pkg[bar] ) !foo? ( cat/pkg )
cat/pkg[foo?]
pkg[!foo?bar] foo? ( cat/pkg ) !foo? ( cat/pkg[bar] )
cat/pkg[foo?]
pkg[foo=3Dbar] foo? ( cat/pkg[bar] ) !foo? ( cat/pkg[-bar] )
cat/pkg[foo=3D]
pkg[!foo=3Dbar] foo? ( cat/pkg[-bar] ) !foo? ( cat/pkg[bar] )
cat/pkg[!foo=3D]
IMO, this is simple enough to understand, and use :)
