The spec would need to require the colons, and probably permit empty
strings in place of the numbers when an OP wanted to say nothing at all
about validation, e.g.

openid.ax.d.c=::+1-555-555-1212

But if we could work our backchannel URLs, we wouldn't need to worry
about making the responses more compact.
