extension

defined as substatement in the module with argument statement as its substatementextension

used inside module

extension declared before container node

extension contained argument

Code Block

collapse	true

module stores {

    typedef year {...}

    book-store:sync-flag "on"; 

    container bookstore {...}

Image Modified

data tree still only has one direct child (container node) as with the standard stores model
value of the argument is not seen?

8

scenario the same as case 1 but the extension was used in the container statement without an argument

Code Block

collapse	true

module stores {
    yang-version 1.1;
	...
    extension sync-flag{
        description "This extension allows to tag nodes with a sync flag";

    }

    typedef year {...}

    container bookstore {
        book-store:sync-flag;
		...

same extension declaration/usage fails for:
- - scenarios in all cases 2-7

9

extension defined as substatement in the module without argument statement as its substatement

extension used inside container statement before all other substatements

no argument declared for extension

Code Block

collapse	true

module stores {
    yang-version 1.1;
	...
    extension sync-flag;

    typedef year {...}

    container bookstore {
        book-store:sync-flag;
		...
        leaf bookstore-name {...}
		list categories {..}

use of the same definition and declaration of the extension on this case for cases #1-7 passes

10

extension defined as substatement in the module without argument statement as its substatement

extension used twiceinside container statement before all other substatements
inside leaf statement (child of container statement)

extension declared has no argument

Code Block

collapse	true

module stores {
    yang-version 1.1;
	...
    extension sync-flag;

    typedef year {...}

    container bookstore {

		...
        leaf bookstore-name {
			book-store:sync-flag;
		}
		list categories {..}
...

Extra Notes:

There seems to be no inheritance of the extension statement for the substatements wherein the extension was used
The date tree and schema tree does not change sizes with the addition of the extensions for all cases shown above
