Surprisingly, you can do this:
<p:viewport name="crazy">
<p:declare-input port="e" step="other" source="result"
select="/doc/x"/>
<p:declare-output port="replacement" step="crazy" source="e"/>
<p:step name="a" type="special">
<p:input port="document" step="outside" source="result"/>
</p:step>
</p:viewport>
In this case, the viewport iterates over the matching 'x' subtrees
in the document but doesn't replace them.
The contained step 'a' should be executed as many times as there
are 'x' subtrees but it doesn't use as input anything in the
viewport and doesn't contribute to the viewport's output.
From and input/output graph flow, it isn't in connected to the viewport
in anyway.
Should we allow this kind of step in iteration (i.e. viewport or
foreach)?
