service inheritance

[Pablo Lalloni <pl...@afip.gov.ar>]

Is there a way to accomplish an inheritance-like relationship between
services?

The case is I would like to customize BuilderFactory service by changing
the implementation of some of its facets, though don't want to miss
future improvements of BuilderFactory nor duplicate all of its spec on
my app sdl... 

Is there a mechanism that allows me to -say- extend a service and
override some of its specification?

Is this posible?

Sounds muuuuch better.

Nothing like this is planned.  Inheritance, in general, is problematic. What might be nice would be
to make BuilderFactory's parameters schema seperate, and introduce a mechanism for extending a
schema (this has been suggested already). Cut-and-paste, for now.
