[SE, ALL] URI squatting; please don't

Folks, I have been working on getting the SE/ODSD primer [1]
to pass the W3C publication rules [2] so it can be put in /TR space.

There were a number of "normal" errors in this document, which
I don't mind fixing (though this does consume time).

But a general problem that I want to highlight for any other
document editors is minting URIs in Web address space
that we do not own.

Specifically, ODSD refers to (non-existent) things in
http://ecommerce.org and http://auctioning.org.  These are
clearly (I think) meant to be examples only.  While the first
domain exists, the second domain is explicitly advertised
as for sale.  Neither is an appropriate place in which to
create new example URIs.

To fix this, I am changing them to ecommerce.example.org
and auctioning.example.org respectively.

Please let's avoid [3]namespace squatting in our documents.
