The other alternative is to write the Distribution Annex to be very
useful in homogenous distributed systems without preventing
heterogenous distibution. This is what we tried to do in Ada 95.
(Came pretty close, AI-208 discussed last week in Paris, deals with
this issue. Paragraph E.2(13) is easy to understand in a homogenous
environment, but is clearly broken for heterogenous implementations.
"..the implementation shall chose the same representation fro the type
upon each elaboration of the type's declaration for different
partitions of the same program." What does this mean for Integer if
two machines have different byte orderings?
