Add value composition to for_each

[jipclaassens]

unit<uint8> Continents := Classifications/Continents
, storagename = "= propvalue(store_Continents, 'storagename')", storagereadonly = "True"
{
	attribute<LatLong>  geometry       (poly);
	attribute<string>   name                  := Classifications/Continents/name;
	attribute<.>        per_grid     (domain) := poly2grid(geometry , domain);
	attribute<World>    World_rel             := const(0[WOrld],.);
	
	container V := for_each_nedv(AsItemName(name), String(ID(.))+'[..]', void, .);
	
	container perContinent := 
		for_each_nedv(
			name
			, 'geometry[V/'+name+']'
			, void
			, LatLong
		);
}
