Question about theory

Is there a good answer to the question of which "version" of the reals
that the PVS type 'real' uses? I'm writing a paper whose intended
audience will include computer algebra specialists who know almost
nothing about theorem proving, and it would be useful to be able
to say something like:

PVS categorises the reals equivalently to Dedkind cuts, or to Cauchy 

The documentation makes no mention of such questions that I can find,
and reading the prelude section on the reals it would appear that
the reals might be underspecified in this regard. Knowing even this
for certain would be useful.
