My view is that xxx is a reference system (not an aliased reference
system but a standardized reference system identifier).  

And that if you want to create a reference to a specific work that the
form xxx(zzz):yyy would be used, where zzz is the standardized work
identifier.

However, yesterday Steve brought up objections to the xxx(zzz):yyy form.
The alternatives as posted yesterday are to put the work some place else
in the reference or to put the work as a separate attribute in the
<reference> element.
<reference work="zzz" osisRef="xxx:yyy"/>

IN NO CASE can there be a reference without a reference system.
