Re: [netmod] removing a node from a grouping

[Balazs Lengyel <[e-mail]>]

So it seems that

   grouping "bar-etc" {
     uses "foo-bar-etc" {
       refine "foo" {
         if-feature never-supported-feature ;
       }
     }
   }

would work. It seems rather similar to a deviation.

Hi Kent,

I'm not sure that sec 7.13.2 of 7950 allows refine to add a when 
statement, although an equivalent solution would be refine it with an 
if-feature statement for a feature that is never enabled.

Neither "when" nor "if-feature" is permitted as a substatement of
"refine".

My reading of 7950, is that you are allowed to refine a node to add an "if-feature".

RFC 7950, section 7.13.2:

The following refinements can be done:

....

   o  A leaf, leaf-list, list, container, choice, case, anydata, or
      anyxml node may get additional "if-feature" expressions.

Thanks,

Ideally, I think that the groupings would be split up, so that they 
build on each other.

   grouping "foo" {
     container-or-leaf "foo" { ... }
   }

   grouping "bar-etc" {
     container-or-leaf "bar" { ... }
     ...  // the "etc" ;)
   }

   grouping "foo-bar-etc" {
     grouping "foo";
     grouping "bar-etc";
   }

Thanks,
Rob

Say there is:

   grouping "foo-bar-etc" {
     container-or-leaf "foo" { ... }
     container-or-leaf "bar" { ... }
     ...  // the "etc" ;)
   }

And the goal is to use the grouping sans the "foo" node.
Can a "when" statement that always evaluates to "false"
do it?

   grouping "bar-etc" {
     uses "foo-bar-etc" {
       refine "listen" {
         when "false()";
       }
     }
   }

Any better ideas?

Thanks,
Kent
