wildcard doesn't work for nil response

 Hi, 

I have XPath assertion for the response below. 

I am only concerned with the Activity and Agent values, so have wildcard enabled and use * for Reason. 

However if reason is returned as nil, this will fail assertion. Is there a way to include nil in the wildcard assertion?

Alternatively, is there a way to have an OR assertion that will allow me to say 'nil OR *'?
