HTTP-REST Schema import Basic Question

I have a system I'd like to manage using the HTTP-REST support in vRealize. 

I've been given an .xsd file that contains only the definitions for the Beans used in the interface and doesn't include any of the GET/PUT APIs.

When I import the file, I don't seem to get any benefit or see any new functionality. 

My question is, what is the format of the schema file?  Can I import a .wadl (Web Application Definition Language) file?

I did a bit of Googling but couldn't find any examples.

     Thanks for my newbie question,
