5.2.5.2 `list` attribute

If you are using an execution context that inherits from the `NameRecorderMixin` (nearly all do -- see chapter 8) then the execution context will raise a `ApplicationError` exception if multiple instances of an `<al-textarea>` tag with the same name are added to a form. The `list` attribute is used indicate that multiple instances are intentional.

The presence of the `list` attribute on an `<al-textarea>` tag makes the request merging in the `NameRecorderMixin` class place any browser request values for the field into a list (field not present is represented by the empty list).
