Further problems with this.. the
attached pipeline uses an XSLT to construct a document, which is then
wrapped in the <delegation:execute> element using XInclude (thus
leaving only business logic in the XSLT), then passed to the delegation
processor.
The resulting document now has *duplicate* namespace declarations, also
making it badly formed:
<return xmlns:delegation="http://orbeon.org/oxf/xml/delegation"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:oxf="http://www.orbeon.com/oxf/processors"
xmlns:xi="http://www.w3.org/2001/XInclude"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:p="http://www.orbeon.com/oxf/pipeline"
xmlns:p="http://www.orbeon.com/oxf/pipeline"
xmlns:xi="http://www.w3.org/2001/XInclude"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:oxf="http://www.orbeon.com/oxf/processors"
xsi:type="xsd:string">No accidents reported.</return>

I've been experimenting with
calling a web service from XPL.
However I notice the example of calling the highway traffic web service
(http://www.orbeon.com/ops/doc/integration-webservices)
can return a
badly formed document, with no namespace prefix declared for the
"xsi:type" attribute:
<return .. xsi:type="xsd:string">No accidents
reported.</return>
To avoid the problem I can declare the prefix 'xsi' in the XPL pipeline
invoking the web service, but this seems totally hacky to rely on this
prefix being delclared like this - eg, if my prefix name doesn't match
'xsi', it won't work.
Is this the fault of the web service or Orbeon?
