RE: xforms:choose/if?

Please note: the methods suggested by this email does NOT work.
The submission attribute is an IDREF, not an XPath expression.

So, submission="if(...)" categorically does not work.

And the xforms:when construct was a 'wanted' feature, not an
available feature.

as I said in my previous email, 
you can but you have to do it differently

instead of
   <xforms:when test="instance('first_step')//count_result = 0">
              <xforms:send submission="ws_1"/>

you need to try
              <xforms:send submission="if(instance('first_step')//count_result 
= 0 ),'ws_1',0)"/>
<xforms:send submission="if(instance('first_step')//count_result != 
0 ),'ws_2',0)"/>

etc...

the syntax might not be quite right but if you do this you will optionally 
select the thing you want done based on the test.
