[netmod] Combining if-feature statements

[Robert Wilton <[e-mail]>]

YANG nodes can have multiple if-feature statements.  Its not entirely 
obvious to me how if-feature statements combine for a given node.  I 
presume that a node is supported if all if-feature statements on the 
node are valid.  Is this the correct interpretation?

I.e. in the example below, "things" container is only supported if both 
"do-things" and "do-more-things" features are enabled.

E.g.

module base-module {
   prefix bmod;

   feature do-things;
   feature do-more-things;

    container things {
     if-feature do-things;
     if-feature do-more-things;
  ...
   }
}

Thanks,
Rob
