Hi,
it's a good question, with no clear answer.
There is the defined() function. Under some circumstances, it can be
used to do what you have in mind. Don't try this though!
The problem with this kind of conditional is that imposes parse order
dependency. The order can shift as your manifest (including modules)
evolves.
The clean approach is to define, in a central location, for each node
wether ssl support is managed. Ask us about hiera ;-)
HTH,
Felix
