-Using multiple inheritance in GF. AR 15/9/2004.
-
-The following diagrams show inheritance between abstract syntaxes in two simple systems.

-Idea of each module:
-
- User -- User's moves on any domain
- System -- System's moves on any domain
- Top -- grammar covering both kinds of moves
- X = Math, City -- possible domains
- UserX -- User's domain specific moves
- SystemX -- System's domain specific moves
- TopX -- all moves on the domain X
-
-In parallel to the abstract syntax hierarchies, we have of course
-hierarchies of concrete syntaxes for any language; this directory contains Eng.
