docs: <p>
  Add a new static variable.
  </p>
  <p>
  These static variables are added to the context before this view
  is processed, so that they can be referenced from
  the context like any other context variables, for example:
  {@code ${myStaticVar}}.
  </p>
  
  @param name the name of the static variable
  @param value the value of the static variable
