Not that I know of, no. Did you have a particular schema language in mind?

Then it sounds like you are asking more about validating individual data
items. Puppet still doesn't have general-purpose schema validation for
such things, but you can write context-specific validation in DSL or as one
or more custom functions.

Not without a particular schema language attached to it. And maybe not
with one. It is not immediately evident to me that describing the expected
form of the data in some schema language and then using that to validate
would be in any way better than writing appropriate validation code in
either Puppet DSL (for use in a Puppet manifest) or Ruby (for a custom
function). You have to write custom code any way you do it, so what is the
advantage of adding another language to the mix?

I suspect not.
