In a class diagram, how to link a Document artifact to a class

[ea1020]

In my class diagram, I have some documentation that applies to many classes.  I put the document link on the diagram, but I would also like to have a connector from the documentation artifact to the various classes that are affected by it.
All connector types, such as trace, information flow, and association try to create a connection with a role, such as "0..1 to 0..*", and when I transform this class model, EA tries to treat the document as if it is a class.
I just want a link to show, to prompt the reader to be aware that this class is affected by the documentation.  How do I do this, without the Transformation process trying to create Foreign Key relationships in the generated DDL model?
