Can I do something like this in the resource file of my LWRP:

attribute :default\_prop, kind\_of: String  
attribute :opional\_prop,  
kind\_of: String,  
default: default\_prop

The idea is I want the property to default to the vaule of another property if it isn’t explicity passed to the resource.

Do I have to handle this programatically in the provider file?
