How does Minimserver build the upnp:AlbumArtURI property for content directories?

Apologies, it's been so long since I decided on how to handle "box sets" that I forgot it's not the "standard".
For me, if a release contains any albums I essentially tag it as though it's a bunch of albums, and have a tag called BOXTITLE where I place the name of the release.

I then have in tagFormat:
Album.displayFormat={$Date^^ - ^$Album^^^$boxtitle^ (from the boxset '^')^}

Whilst I can't browse the release as a single entity, it's very rarely that I want to do that, and tagging them as individual albums allows me to search for the album by name and see in the album list all the versions I have of that album e.g.

Sgt. Pepper's Lonely Hearts Club Band (from the boxset 'The Beatles')
Sgt. Pepper's Lonely Hearts Club Band (from the boxset 'The Beatles In Mono')
Sgt. Pepper's Lonely Hearts Club Band (Super Deluxe Edition)

Viewing an album does look a little strange as typically the discnumber will be >1, but the boxtitle in the album name reminds me that it's part of a bigger release.

In short, ignore my previous post.
