I believe you are correct. The ils-di stuff is just kind of a framework
starting point, not (yet) a complete end-to-end standards-constrained
solution.
I believe you will find my thoughts and experiences on this issue
helpful. My own circumstances did not involve collection-level
anything, but I still ended up using an unholy mish-hash of several
abused metadata formats to express what I needed.

I'm working with the University of Oxford to look at integrating some library
services into their VLE/Learning Management System (Sakai). One of the services
is something that will give availability for items on a reading list in the VLE
(the Sakai 'Citation Helper'), and I'm looking at the DLF-ILS GetAvailability
specification to achieve this.
For physical items, the availability information I was hoping to use is expressed at the level of a physical collection. For example, if several college libraries within the University I have aggregated information that tells me the availability of the item in each of the college libraries. However, I don't have item level information.
I can see how I can use simpleavailability to say over the entire institution whether (e.g.) a book is available or not. However, I'm not clear I can express this in a more granular way (say availability on a library by library basis) except by going to item level. Also although it seems you can express multiple locations in simpleavailability, and multiple availabilitymsg, there is no way I can see to link these, so although I could list each location OK, I can't attach an availabilitymsg to a specific location (unless I only express one location).
Am I missing something, or is my interpretation correct?
Any other suggestions?
Thanks,
Owen
PS also looked at DAIA which I like, but this (as far as I can tell) only
allows availabitlity to be specified at the level of items
