Threading and ordering

XProc 1.0 says:

  Note that a p:input or p:output element may contain more than one
  p:pipe, p:document, p:data, or p:inline element. If more than one
  connection is provided, then the specified sequence of documents is
  made available on that port in the same order as the connections.

Now that I'm contemplating a multi-threaded implementation, that seems
like a pretty significant burden.

Has anyone written a pipeline that depends on this ordering?

                                        Be seeing you,
                                          norm
