SFX uses a proprietary mechanism to trigger fetch that is not part
of the OpenURL standard. The usefulness of this mechanism, however,
motivated the very rich fetch functionality in the 1.0 version of the
standard- if you care at all about interoperability you should avoid
the SFX trigger mechanism.
COinS recommends not to use ContextObjects with fetch (by reference
metadata) because it is thought that deverse agents will not be able
to deal with them; however, link server systems with full Z39.88
implementations should have no problem with them.

I'm certainly no expert, but my understanding is that you have to
embed the extra authors into a call (a "fetch" in the SFX lingo) using
a private identifier at the end of the OpenURL string. It's more
complicated than that, of course, since there has to an sid included
in addition to the pid and, at least in the SFX-biased documentation,
this so-called "fetch" operation is intended to be done using z39.50
or html-based (REST?) calls to a dataserver determined by the source.
Pretty messy, huh?

The upshot is that multiple authors aren't directly supported in COinS
because a COinS url is by design generic and therefore can't know
about how to deal with the specific sid and pid requirements of a
fetch.
However, I would think Umlaut ought to be able to handle it since it
has SFX at its core.

Can you tell me how to legally include more than one author name
in an OpenURL context object? I've been a bit confused about this
myself, and happen to be dealing with it presently too.
