Remarks
A relationship must be given a name and may optionally be given a description. The description can include information that describes the nature of the relationship between the categories (for example, an "accessory" or "add-on"). Relationships are one way, that is, if category A has a relationship to category B that does not create a reciprocal relationship from category B to category A.
When multiple relationships are created between the same two categories, each relationship must have a unique name.
