I suggest just like yang-data:

module: example-module

  structure address-book:
    +-- address* [last first]
       +-- last      string
       +-- first     string
       +-- street?   string
       +-- city?     string
       +-- state?    string

I will add text to the draft that defines this.

I have added support for this on the branch feature/yang-structure.
It verifies the grammar and adds the option --tree-print-structures.
It doesn't handle augment-structure yet.
