Link in goat diagram

Is there an easy way to include a link in a goat diagram?
what I found so far: all major browsers support [XLinks in SVG]. So it seems doable for goat as it builds an svg.
Though not much documentation is available for goat. If there is no native solution could you advise on how to approach the development of such a feature in goat or is it a “dead-end” and such a feature is not approachable by design.
Goat defines runes in the source code, should there be one for links?

Not that I know of, but you should probably raise the question here:

@jmooring did that, thank you!
