1. A valid browsing context name or keyword is any string that is either a valid browsing context name or is an ASCII case-insensitive match for one of:
   1. _blank
      1. Usually a new tab, but users can configure browsers to open a new window instead
   2. _self
      The current browsing context (Default)
   3. _parent
      1. The parent browsing context of the current one
      2. If no parent, behaves as _self
   4. _top
      1. The topmost browsing context
      2. To be specific, this means the "highest" context that's an ancestor of the current one
      3. If no ancestors, behaves as _self
2. Browsing contexts can have a browsing context name
3. By default, a browsing context has no name (its name is not set)
