/ Alessandro Vernet <avernet@orbeon.com> was heard to say:
| What does $status refer to in the pipeline? Would that be a parameter
| of the pipeline?

Yes, sorry. That was just a global, statically known parameter.

| One way of looking at tests evaluated at runtime is
| the following: we will want to have tests that run on infosets
| manipulated in the pipeline. So as we have an attribute on <p:input>
| to reference a named infoset ("use" in your example), we can use the
| same attribute on the <p:choose>. Then it would be quite natural to
| use XPath to perform the actual test. So the expression in the <p:when
| test="..."> would be an XPath expression evaluated in the context of
| the infoset referenced on <p:choose>.
| Say:
|     <p:choose use="some-document-label">
|         <p:when test="/status = 'draft'">

Ah, yes, I like that.
