 //! A simple DOM where every node is owned by its parent.
 //!
 //! Since ownership is more complicated during parsing, we actually
 //! build a different type and then transmute to the public `Node`.
 //! This is believed to be memory safe, but if you want to be extra
 //! careful you can use `RcDom` instead.
