Multiple Taxonomy References in Same Content Type

I have a content type that must have two fields where a user can choose terms from the same vocabulary.

For example, an organization's "product" content type must have a reference to a "product categories" (multiple select) taxonomy vocabulary AND it must have a reference to a "primary product category" (only one selection allowed).

"Product categories" and "primary category" should point to the same taxonomy vocabulary, so that when I change one term in a vocab, I don't have to change the term in the other. AFAIK I can only have one reference per content type to a single taxonomy vocabulary, and that is set in the taxonomy vocabulary itself, not in the content type.

I found content_taxonomy module, which allows me to set references to taxonomy vocabularies as content fields in CCK. Using this I can accomplish the above. However, I need to extract info from the $node object in a feed, and setting terms using content_taxonomy does not allow me to extract the term name from the $node object. I only get ids of the taxonomy terms like this:

            [field_gd_categories] => Array
                (
                    [0] => Array
                        (
                            [value] => 1
                        )

                )

I could, of course, make a database call to get the taxonomy term, but that defeats the purpose of using a view to generate the feed. I might as well query the database manually for the feed in the first place.

So:
Is there a simpler approach to do what I am trying to do without using content_taxonomy?
