Right.  I was answering from an "Ada language" perspective, and you were
answering from an "available implementation" perspective.

I hope the OP now understands what's what.  ;-)

The Distributed Systems Annex is one of the "Specialized Needs Annexes"
(annexes C, D, E, F, G, and H), which are optional, in the sense that
an implementation can conform to the Ada standard without implementing
all of these Annexes.  Here's the RM wording:

7  The following Specialized Needs Annexes define features that are
needed by certain application areas:

8     Annex C, "Systems Programming"

9     Annex D, "Real-Time Systems"

10    Annex E, "Distributed Systems"

11    Annex F, "Information Systems"

12    Annex G, "Numerics"

13    Annex H, "High Integrity Systems"
...

17    All implementations shall conform to the core language. In
addition, an implementation may conform separately to one or more
Specialized Needs Annexes.
