<p>Hi,<br /><br />I have seen the ticket in JIRA. But to be sure to be
understood, I give an other example.<br /><br />I would find a way to write
this DRL code :<br /></p><pre>Person( age ( (> 30 && < 40) ||
(> 20 && < 25) ),name == 'DOE' )</pre><p><br />In DSL code like
this :<br /></p><pre>There is a Person with</pre><pre> ((- age is less than
40<br /> - age is more than 30)<br /> or<br /> (- age is more than
20<br /> - age is less than 25))<br /> - name is 'DOE'</pre><p><br
/>Thanks andy for the ticket post :)<br /><br />Stephane</p><p></p><p>
