  * ## Configuring ngPluralize
  * You configure ngPluralize by providing 2 attributes: `count` and `when`.
  * You can also provide an optional attribute, `offset`.
  *
- * The value of the `count` attribute can be either a string or an expression; these are
- * evaluated on the current scope for its bound value.

  * ## Configuring ngPluralize with offset

+ * a number by any desired value.

  * Let's take a look at an example:
  *
  *    <ng-pluralize count="personCount" offset=2
  *                  when="{'0': 'Nobody is viewing.',
- *                         '1': '{{person1}} is viewing.',
- *                         '2': '{{person1}} and {{person2}} are viewing.',
- *                         'one': '{{person1}}, {{person2}} and one other person are viewing.',
- *                         'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
+ *                         '1': '${person1} is viewing.',
+ *                         '2': '${person1} and ${person2} are viewing.',
+ *                         'one': '${person1}, ${person2} and one other person are viewing.',
+ *                         'other': '${person1}, ${person2} and {} other people are viewing.'}">
  *    </ng-pluralize>
  *
  * Notice that we are still using two plural categories(one, other), but we added
  * three explicit number rules 0, 1 and 2.
- * When one person, perhaps John, views the document, "John is viewing" will be shown.
- * When three people view the document, no explicit number rule is found, so
- * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
- * In this case, plural category 'one' is matched and "John, Marry and one other person are viewing"
- * is shown.

- * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
- * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
