I wondered whether the original design intended to map
decoration differently for predicates and expressions?
Then the user could determine the mapping of e.g. S'
as either
mk_z_schema_pred (S, ')
mk_z_schema_pred (mk_z_decor%down%s

I'm sure it is.
But I doubt that it is

My guess would be that a non-empty decoration is possible for
Z'SchemaPred to allow for variable decoration during proof operations:
if all variables in the characteristic binding are consistently
decorated, the resulting term is still Z.
However, not all Z proof operations consistently

I need to remind myself exactly what the decoration in
mk_z_schema_pred is for (I know what the semantics is
intended to be but I
