-- External References --
-------------------------
-- External references influence the way a project tree is processed (in
-- particular they provide the values for the typed string variables that
-- are then used in case constructions).
-- External references are project-tree specific, so that when multiple
-- trees are loaded in parallel we can have different scenarios (or even
-- load the same tree twice and see different views of it).
