Hi Markus, Thanks for this - we'll have a look.
In the meantime, you can still run the service with the original Xpath expression (/ns3:directoryContents/ns2:file/@xlink:href) even if HealthChecker is complaining. You can also set in preferences to do only "quick checks" when running a workflow instead of "full checks" which will make the HealthChecker warning go away.
