- A ZCML ``view`` directive (and the associated ``bfg_view``

  decorator) can now accept a "wrapper" value.  If a "wrapper" value
  is supplied, it is the value of a separate view's *name* attribute.
  When a view with a ``wrapper`` attribute is rendered, the "inner"
  view is first rendered normally.  Its body is then attached to the
  request as "wrapped_body", and then a wrapper view name is looked up
  and rendered (using ``repoze.bfg.render_view_to_response``), passed
  the request and the context.  The wrapper view is assumed to do
  something sensible with ``request.wrapped_body``, usually inserting
  its structure into some other rendered template.  This feature makes
  it possible to specify (potentially nested) "owrap" relationships
  between views using only ZCML or decorators (as opposed always using
  ZPT METAL and analogues to wrap view renderings in outer wrappers).
