I think what you want is access to the dictionary's items() right?

<!--#in "dictionary.items()"-->
  <!--#var sequence-key--> : <!--#var sequence-item-->
<!--#/in-->

The mapping attribute is not relevant here. It means treat
sequence-items as mappings not instances, that is to say, look up vars
with __getitem__, not __getattr__.
