Ok.  I think we have three cases then:

  (1) xen emulation using xenner (default, with or without kvm).
  (2) running on xen, with xend creating the domain, and
  (3) running on xen, with qemu creating the domain.

For (2) and (3) we need command line switches to enable these modes.
Specifying a domain ID makes sense in all three cases though.  So I'd
keep the -xen-domid switch, like this:

  -xen-domid <nr>    specify xen domain id.
  -xen-attach        attach to specified domain (created by xend).
  -xen-create        create the domain directly.
