Adding 'OR' constraints to fact's properties in DSL

I would like to write something like this :

There is a Cheese with
( - age is less than 42
or

• age is more than 60 )
• type is 'stilton'

Unfortunately, It's the drools parser which manage "-" char.

Also this previous synthax don't work in the LHS.

Anyone could help me to do an equivalent condition in my DSL ? If possible with "-" sugar char.
