OK, that's good.

It should display them all, no?

The real question is whether it's legal to have multiple <atom:link>
elements with the same relation, media type and language.  From a quick
look at the most recent draft, I see nothing forbidding it.

Ideally, if there were more than one, you'd want to be able to give each
rel="payment" link a title attribute, say (or string content to be
interpreted as a title).  I'm not sure if either of those are legal for
an extension, but I'm no expert here.
