Purpose
=======
The attribute name isn't required on the <filter> tag. If not set, it can't be selected with a xpath and it can't be overwritten.
A lot of PR are coming from the community just to add a name on a filter because:
- It can't be selected with a xpath.
- It can't be used with `default_search_foo` on an action context.
Specification
=============
Make the atttribute name required
