Hello again,
From this link:
file://localhost/Developer/Documentation/Essentials/SystemOverview/Framework
s/index.html
I found this text...
Frameworks solve this problem by bundling a dynamic shared library with the
resources used by the library or otherwise related to it. Indeed, "bundling"
is an apt term because frameworks are bundles as much as applications and
plug-ins are. However, frameworks differ in some significant ways from other
types of bundles:
* Frameworks include a unique type of resource header files. They can
also contain as a resource anything else that is appropriate, such as
private static libraries.
* The bundle bit is not set when a framework is built. As a result, the
Finder does not treat the framework as a file package a directory presented
as a file and thus developers can browse the packaged header files.
* Frameworks are versioned bundles, which are described in "The Internal
Structure of Frameworks".
So according to the docs, frameworks are like plug-ins. It is these same
docs that talk about the linking. I misread them earlier in that I mixed
the linking up with the dynamic loading.
Anyway, the docs imply that frameworks are like plug-ins, so wonder what the
real story is?
Finlay, do you have any more links into the docs that might shed some more
info?
Thanks,

Depends what you mean by "bundle", but in the terminology Ondra was
