try/catch not behaving correctly in pipeline. No way to retrieve the c:error elements within c:errors

Why in the world I would get following output from this pipeline using 
calabash?


**************OUTPUT****************
<c:errors xmlns:c="http://www.w3.org/ns/xproc-step"/>

Should I not receive <c:error> children in here?
