[CONNECT Update 16] What replaces Engineering Links?

Engineering Links let us attach a hyperlink to a DGN element.  Engineering Links use tag technology and Bentley Systems tell us that they are deprecated.  Help tells us: It is recommended that you use Explorer and Link Sets to manage collaborative project data over the Internet.

However, as far as I can see, Link Sets don't apply to DGN elements.  What is the non-deprecated alternative to an Engineering Link?
