I'm not sure you mean when you say "type-file definition". Could you clarify?
If you can/are willing to share, it would help to be able to see your
type/provider code.
Here's a gist with a minimal implementation of this functionality, which
hopefully will make it clear where your code differs (and if it really doesn't
differ, we have a truly fascinating mystery on our hands!):

`validate do` is basically just a convention to do something like `validate if
respond_to? :validate`. It defines a validation block, which is then used
implicitly by Puppet as part of applying the catalog. It could also have been
implemented by having Puppet call any given "validate" method, if one is
provided. I suppose the reasoning was that this way seems less like magic and
more like an obvious part of the type API; I'm not entirely sure.
