RE: Implicit CPP/CPA for Registry and Registry client

[Martin W Sachs <mwsachs@us.ibm.com>]

Any instance document is a specialization of the spec in the OO sense.

The implication of "specialization", however, is that something may be
missing that is needed for the Registry CPP. Should you identify a real
hole in the TP spec, the hole will have to be filled though maybe there
won't be time before Vienna.

So, get out your fine-tooth comb and let us know what it picks up.

Regards,
Marty

Specialization in an OO sense. Suggesting the TP spec is the
generalization.


I carefully used the word "could".  The need for a specialized Registry CPP
is not concrete, but analysis would determine if a specialization is
needed.
Hopefully not.  Its time to dig deep into the TP spec to find out (I intend
to read it with a fine tooth comb).

back again too.
What do we mean anyway by "specialization"? What is so special?

I am back for a few minutes.

Why do we need a word for this?  Why can't it be simply a Registry CPP, and
Registry CPA, which could be a specialization of the TP specifications (if
specialization is required that is to say).

I am OK with dropping the word implicit to avoid confusion. Should we
replace
the word "Implicit" with the word "Template" (as in template CPP or
template
CPA).

I am assuming we are OK with the basic approach of the spec which is to
define a
template CPP for registry and for client and a template CPA between the
registry
and registry client.

Let us know if anyone disagree with above assumptions.
