Currently, certain RSS and Atom elements can be populated only by making use of the "low-level" feed framework; this is particularly annoying in the case of certain common items such as the RSS category element. Ideally, all valid elements could be populated by use of the high-level framework, but in practice perhaps it would be best simply to determine which elements are needed in the most common use cases, and provide access to them.
One possible implementation would be to extend the high-level framework's use of the template system; instead of providing templates for the title and description elements, perhaps the high-level framework could allow specification of a template for the complete item element. For example, a publisher who wished to list the categories to which items belong would be able to include this in the template for items in an RSS feed:
{% for category in obj.get_category_list %}
<category>{{ category }}</category>
{% endfor %}
