([[Tags already receive a special rel-class|todo/rel_attribute_for_links]].) This means there is a general need for a syntax to specify user-defined rel-classes on wikilink (then bug deps would simply use their special rel-class, either directly, or through a special directive like `\[[!depends ]]`), and to refer to them in pagespecs (in forward and backward direction). Besides pagespecs, the `rel=` attribute could be used for styles. --Ivan Z. + +> FWIW, the `add_link` function introduced in a recent +> release adds an abstraction that could be used to get +> part of the way there to storing data about different types of +> links.
