To add another dimension to the discussion, the word
"package" in the field of software can also mean
a package of software for distribution, such as an
RPM package.  Authors who deal with packaging software
but not APIs will perhaps misuse a <package> element.
The advantage of the oo* names is that they are
specific to their subfield.
