Hi,

On page 24 of the PDF document "Kentico CMS Developer's Guide 3.1a" dated August 6, 2008, there's a bullet stating that:

* Relationships: It's now possible to add custom fields and custom (XML) data to the relationships
(the feature requires custom-developed user interface).

I don't see this feature documented anywhere else. Could you point me to some documentation or explain how it is used?

Thanks.
