The contents already encode multiple addresses. We shouldn't have multiple ways to say the same thing.

@enygren I believe you added this language in 9e1726c. Do you think it's still needed?

I think if we address issue #95 and just recommend using a multi-value parameter (and have very clear specification that duplicate parameters must ignored in a deterministic manner) that this text isn't needed as-is.

Should we replace this with text elsewhere prohibiting the same parameter key from being used multiple times and specifying that one (first? last?) should be deterministically selected?

(so pend this on #95 and close/wontfix if we merge that, or approve if we reject #95)
