You *could* return a dictionary from a DTML method:

DTML Method 'return_dict'::

  <dtml-return expr={ 'foo' : 0, 'bar' : 1 }

DTML Method 'show_dict'::

  <dtml-var standard_html_header>
  <h2><dtml-var title_or_id> <dtml-var document_title></h2>

  <dtml-let dict=return_dict>

  <p> Foo: <dtml-var "dict['foo']">

  <p> Bar: <dtml-var "dict['bar']">

  </dtml-let>

  <dtml-var standard_html_footer>

....but I can't imaging wanting to.  Try to rearrange your
stuff so that the code generating the mapping can call
'manage_changeProperties()' its own self, or else move
it to PythonScripts/PythonMethods/ExternalMethods/a Product;
you'll be glad you did.
