There are several overlapping notions of what it is to be a conceptual work, and I think that the FRBR version is very much a compromise ("super-works" fill in some of the gaps from above).
I do believe that all theoretical models require that a work have a creator [I am persuaded by arguments that the coming in to existence of a work rigidly depends on the existence of it's creator, across modal contexts, but that's not strictly relevant here :-)].
It is less clear that a work must have a title, or that uniform titles as currently constituted are the exact corresponding concept to what a work title would be.
The published FRBR model has some logical inconsistencies (how much does a manifestation weigh?), and is best treated as a source of inspiration, rather than as literal truth.
Wittgensteinian family resemblances, prototype theory, and inheritance with overriding can be a useful way of looking at things, especially from a bottom up perspective.
It's also worth reading Barbara Tillett's full dissertation, which laid the groundwork for the IFLA report. I got permission to scan and pdf this a while ago; (hey Jenn, can I borrow the scribe for a bit).
I think Karen was on the other end of a conversation where I found an LC record claiming two distinct uniform titles.

However, the Work title is not the same as the title of the "instance" and most current library records do NOT have a Work title (and thus are not easy to fit into FRBR).
