(9) CompletionProof (UPPER BOUND(ID) transformation)

The transformation into a RNTS is sound, since:

(a) The obligation is a constructor system where every type has a constant constructor,

(b) The following defined symbols do not have to be completely defined, as they can never occur inside other defined symbols:


sel

(c) The following functions are completely defined:

activate
from
first
s

Due to the following rules being added:
none

And the following fresh constants: none
