Add GRAMMARS into RESTEasy WADL

Request from user:

{{Sorry for bothering you, but I have a question about the Resteasy WADL generator.

I already created a post on StackOverflow but with little response: https://stackoverflow.com/questions/44112418/missing-grammar-in-jboss-resteasy-generated-wadl

I only want to know how to get the WADL generator to generate the GRAMMARS part of the WADL.
I only get the RESOURCES part without the element attribute, nor the GRAMMARS.

Is the current implementation capable of generating the grammars and if so, what do I need to do to get it in the WADL?

Thank you very much for your time! }}
