RE: The default readable port in a for-each?

I agree with Mohamed on this one. And, obviously, the same applies to p:viewport as well.

 Well
 
 I would say it is covered by
 
 2.5 Environnement
 
 [[
 

 * If there is a preceding sibling step element:

  * If that preceding sibling has a primary output port <http://www.w3.org/XML/XProc/docs/langspec.html#dt-primary-output-port> , then that output port becomes the default readable port <http://www.w3.org/XML/XProc/docs/langspec.html#dt-default-readable-port> .

  * Otherwise, the default readable port <http://www.w3.org/XML/XProc/docs/langspec.html#dt-default-readable-port>  is undefined.

 ]]
 
 That means that the input of "second" is the output of "first"

  Consider:

     <p:identity name="second"/>

  The description of p:for-each says:
  
   The environment inherited by the contained steps of a p:for-each is
   the inherited environment with these modifications:
     * The port named "current" on the p:for-each is added to the
       readable ports.
     * The port named "current" on the p:for-each is made the default
       readable port.
  
  In the case of the identity step named "first", this clearly has the
  desired consequence: first reads the current port of the loop.
  
  In the case of the identity step named "second", to what is the
  "source" port bound?
  
  I think our spec currently says that it's bound to the current port of
  the loop, but I'm not sure that's what we want.
