Is being about something  a property that is applicable to everything that
exists, or is something more required? The commonly held view, at least as
it applies in this context, is that the second condition is required.

A commonly used example is that an Antelope, running free across the
plains, is not "about" anything. However, an Antelope on display in a zoo
becomes a Document that provides evidence as to what an Antelope is (or
what someone means by "Antelope"). See e.g.
http://people.ischool.berkeley.edu/~buckland/whatdoc.html

It is the act of being declared to be "about" a "subject" makes the
Antelope be also a Document.... just like using a property with a given
domain on something allows you to infer that it has that domain as one of
its types.
