  [#folding-attributes]
  As an experimental feature, predefined attributes for character replacements like `+++{plus}+++` or `+++{quot}+++` and attributes are foldable as well.
  Attributes need to resolve to single declared value to be folded.
  Folding is also available for HTML entities (like `\&amp;`) and unicode characters (like `\&#x2020;`).
  As an experimental feature, the user needs to enable it in the settings of the plugin.
  
  Clicking on a folded attribute to unfold it.
  The hotkey to unfold one element is kbd:[Ctrl+NumPad+], the hotkey to fold one element is kbd:[Shift+NumPad-]
  The hotkey to unfold all elements is kbd:[Ctrl+Shift+NumPad+], the hotkey to fold all elements is kbd:[Ctrl+Shift+NumPad-].
  
  // see: AsciiDocStructureViewElement
  The structure of the file kbd:[Alt+7] shows the hierarchy of sections and blocks with titles.
  This contains (if available) the first block attribute element (like \[source], \[quote] or \[verse]) and the title of the block or section.
  If an element like an `image::[]` references another file, it shows the icon and the name of the file.
  If an `include::[]` references an AsciiDoc file, it includes the file as a sub-tree in the structure view.
  Clicking on either a referenced file or an element of a sub-tree opens the referenced file.
  
negative.code: Currently, it adjusts empty lines around headings, lists and blocks.
  It also adjusts spaces around list items.
  
  By default, it re-formats blocks to the one-sentence-per-line convention.
  The user can disable this in the code style settings.
