Set properties and attributes for the containing DOM element. Doing it this way
as opposed to setting them directly from node() allows changing them later on
without recreating the element itself. Also, code can be more readable this way.
Note that when a nested observe() is used, properties set this way do NOT
automatically revert to their previous values.
