/* The <Collecting> protocol is root of the collection protocol heirarchy.
The <Collecting> protocol defines the most general interface to a
collection of elements. Elements can be added, removed, and replaced.
The contents can be tested, enumerated, and enumerated through various
filters. Elements may be objects, or any C type included in the
"elt" union given in elt.h, but all elements of a collection must be of
the same C type.
