(7) CompletionProof (UPPER BOUND(ID))
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:

   U11'_3
   U12'_3
   U21'_3
   U22'_3
   PLUS_2
   X_2
   ACTIVATE_1

(c) The following functions are completely defined:

   U11_3
   U12_3
   U21_3
   U22_3
   plus_2
   x_2
   activate_1

Due to the following rules being added:

   U11(v0, v1, v2) -> 0 [0]
   U12(v0, v1, v2) -> 0 [0]
   U21(v0, v1, v2) -> 0 [0]
   U22(v0, v1, v2) -> 0 [0]
   plus(v0, v1) -> 0 [0]
   x(v0, v1) -> 0 [0]
   activate(v0) -> 0 [0]

And the following fresh constants:    const, const1, const2, const3
