Abstract: Specification Approach
As is common in programming, it is possible in ALF to work with abstract sets
and operations rather than with their actual inductive and recursive definitions.
Thus, we may specify abstract structures and operations, which consist of a collection
of propositions implicitly characterizing a number of sets and operations
on them (such a specification is usually given by a set of equations).
When writing the proof, we used this approach in order to work in a modular
style,... (Update)
