We currently say:

   Definition: A pipeline is a set of components connected together, with
   outputs flowing into inputs, without any loops (no component can read
   its own output, directly or indirectly).

Some of the people at DocEng asked why we have this restriction, 
especially given that we don't place any restriction on how URIs are 
resolved: although we say that there aren't any loops, it would be 
possible to access a document (via a URI) that is, in fact, generated by 
the very pipeline that is accessing that document. So although we say 
that there aren't any loops, because we don't say anything about URI 
resolution, we can't guarantee that they won't be.

Cheers,

Jeni
