What does putting it in a element do that putting it in an anchor won't?
The goal is to give an URL when/where a bitcoin address is needed, because URLs are generally shorter and easier to memorize than bitcoin addresses. I don't have any particular preference for
elements over anchors (
... elements) do you have an example of how to transform an URL into a bitcoin address using anchors? Maybe the vCard format could be extended to announce someone's bitcoin address.
I would also like to clarify that although I'm using
bitcoin:xxx URI format in my example, this isn't the point. Use
bitcoin://xxx?label=foo if you prefer, or whatever, it doesn't matter here. The choice of a particular URI format is off-topic here this question is debated in length in other threads.
A similar goal would be to discover bitcoin addresses from a JID (XMPP identifier). I've started to work on
something to address that.
