| Hi all,
| The description of error err:XS0022 says:
| "In all cases except the p:output of a compound step, it is a static
| error if the port identified by a p:pipe is not in the readable ports of
| the step that contains the p:pipe."
| Perhaps I am just having a block here, but can somebody give me an
| example why do we need to make exceptions for compound steps?

The set of readable ports doesn't include the ports of children elements.
But p:output *does* read from the output of its children.

Does that help?

                                        Be seeing you,
