[closed] Re: Section 5.11 unnecessary complex?

Per the discussion at the 9 Apr 2009 telcon, following our resolution
of issue 100, the text of section 5.11 *is* describing an exception.

A p:pipe inside a p:output on a compound step is allowed to connect to
ports that are not in the set of readable ports. 

So, the prose is correct, we decided.
