Chuck is right. I have something more into the lines:
Product <--->> ProductOption <<---> Option <--->> OptionValue
... where Option is something like "Display Type" and OptionValue is something like "Monochrome". And ProductOption is just a proxy table for the many-to-many relationship.
Maybe I should have two more relationships:
OptionValue <--->> OptionRequire
OptionValue <--->> OptionExclude
An AJAX interface would be preferable, so the user gets an error message when changing the selections, not when the application saves the context...
Cheers,
Flavio
