Browse source 
- Node position is public. It represents the node's first character
  index in the document.
- Tree offset is private. It represents the distance between the tree's
  first character index and it's parent's first character index.
- Tree padding is private. It represents the amount of whitespace
  (or other separator characters) immediately preceding the tree.
