[Bug] - SimplePlugin - Foreign Key attribute value is never found within a SetAttribute definition.

Description

An attribute declared within a SetAttribute such as:

          new SetAttribute(
            new MailAttribute(
              _('Alternative addresses'), _('List of alternative mail addresses'),
              'gosaMailAlternateAddress'
            )
          ),

is never found if referenced via a plForeignKey due to simplePlugin->BrosweForeignKey method which wait for a positive boolean return from ForeignKeyCheck.

ForeignKeyCheck is using AttributeAccess with field and values to verify the content and return TRUE if matched. In case of a SetAttribute sub attribute element, the passed value to the AttributeAccess is an array and not a string.
