I must be overlooking something ... I don't see any mention/discussion of mirroring in any of the referenced articles, or anywhere else for that matter. Where in BOL did you find the 'right' answer to this? (I got the mirroring one wrong, too!)
I know when I wrote this question that it was mentioned in one of those references that I listed... but I can't find it in either.
However, in Prepare a Mirror Database for Mirroring, in the Limitations and Restrictions section, it mentions that the only databases you cannot mirror are master, model, msdb, tempdb and databases that are in an Always On Availability Group. Implying that all other databases can be mirrored.
I also notice a small error in my explanation. For the first reference, it should be "Contained Databases" and not "Create Table". (The link correctly goes to Contained Databases.)
