I do not see it in the man page.

For a simple protocol, we might be able to specify that.  We do not
allow astronomical names.  It is only ra and dec.  Also, I think SIA
v1 does not require encoding.  That is the nice thing about simple
protocols: no thinking required.

But really, my main complaint is that it is yet another syntax.
