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