Primary Vocabulary Selection When Selecting Multiple Vocabularies for a Node

Description : With multiple vocabularies available, a node may be associated with more than one vocabulary.

Problem : One of the vocabularies selected may be more of a primary vocabulary, or more relevant, than the other selections. In other words, while all associated vocabularies are relevant, one may carry more weight for the node.

Suggestion : When a node is entered and associated vocabularies are selected; indicate which vocabulary is primary. A method of prioritizing associated vocabularies.

Advantage : The advantage to having multiple categories visible with the node is to allow a user to see relevant nodes. With a primary vocabulary, a user may see nodes which may be more relevant compared with nodes of other vocabularies.

Example : A node is 'Canned Beans are Good for You.'
Vocabularies associated with this node are: vegetables, canned food, and health.
With the ability to have a primary vocabulary, I would select 'health' as primary for this node.
I see that if someone is interested in that node, they are likely more interested in health than vegetables or canned food.
