PSS — New PSS Issue: Interface Inheritance

In the PSS specification (orbos/99-07-07), no provision is made for
[abstract] storagetypes or [abstract] storagehomes to inherit from
interface definitions. It appears this is an oversight as the omission
does not seem reasonable. I have found cases in which a home would
expose the same interface as a storage object, where the home
subsequently delegates to a specific object however selected.
Interfaces are a perfect mechanism whereby the operational signatures
could be standardized, thus eliminating potential errors caused by
changing one but not the other. Since storage objects are assumed to
exhibit only local interface behavior, it would not matter whether the
inheritance was from a local or remote interface definition. This could
be accomplished using a supports clause in the inheritance specification
similar to that of valuetypes.
