One analogy I use is the following:

A person needs to send a message to someone else so they hire a messenger.
The messenger gets in his vehicle (i.e. his port) and starts it (class:
is it a gas car?  an electric one? some thing else?  Internally they all
start differently) and gets on the road that takes him to where he is going
(bucket: more than one type of vehicle can travel on a road, however, each
road has its own rules, etc.).

Please do!

TeX-info is the official text processor for gnu projects.   However, I
know nothing about DocBook.
