are edited to allow for glued Prep+DefArt, using new categories NP',Det',Quant',
Predet',DAP'.
The previous NP.s : Case => Str*Str allows parsing
"in dem Meer" = in_Prep ++ (np.s ! Case).p1
"im Meer" = in_Prep ++ (np.s ! Case).p2,
but since only one of the strings of (np.s!Case) is used, the tree
contains a metavariable like ?2 (the grammar is "erasing"). (Similarly, if we used
NP.s : Case => Str and NP.s2 : Case => Str.)
To get rid of the metavariables, we have to choose BY A PARAMETER, say
NP.s : droppedDefArt? => Case => Str
Using np.a = Ag g n p, the preposition can select between preposition
alone or preposition with definite article (glued or not), via
Prep = {s : GenNum => Str ; s2 :Str ; c : Case ; isPrep : PrepType }
The combination is done in appPrepNP' and appPrep'. This is
independent of the number of glued Prep+DefArt. But LangGer compiles
now in 200s using 30% memory (without SlashV2VNP). Can AppPrepNP' (and
insertObjNP') be simplified?
