+   * @description
+   * HTML5 tel input validation.  Will display a text input in browsers that do no yet support tel inputs. 
+   * Sets the `tel` validation error key if the content is not a valid telephone number.
+   * 
+   *
+   * @param {string} ngModel Assignable angular expression to data-bind to.
+   * @param {string=} name Property name of the form under which the control is published.
+   * @param {string=} required Sets `required` validation error key if the value is not entered.
+   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
+   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
+   *    `required` when you want to data-bind to the `required` attribute.
+   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
+   *    minlength.
+   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
+   *    maxlength.
+   * @param {string=} ngPattern Sets `pattern` validation error key if the value does not match the
+   *    RegExp pattern expression. Expected value is `/regexp/` for inline patterns or `regexp` for
+   *    patterns defined as scope expressions.
+   * @param {string=} ngChange Angular expression to be executed when input changes due to user
+   *    interaction with the input element.
