Paul,

That Calabash is complaining is actually correct. Calumet makes a number
of Calumet-specific steps available by default, without needing to
import any library. That means that Calabash does not know the
declaration of emx:message in your pipeline. On the other hand, because
the pipeline imports the Calabash extension library, Calumet has enough
information about the declaration of cx:message.

I think the best solution for the moment is to use the use-when
attribute instead of p:choose:

<emx:message p:use-when="...Calumet...">
  <p:with-option name="message" select="concat('collection : ',$file)"/>
</emx:message>
<cx:message p:use-when="...Calabash...">
  <p:with-option name="message" select="concat('collection : ',$file)"/>
</cx:message>

Another way to make the step work in Calabash would be to import the
Calumet extension library. The only problem with that is that the
library is available only in the Calumet JAR... I think we should make
it available as a separate file as well, so that you can use it with
other XProc processors.

Vojtech
