getting "n album" view in "AlbumArtist" order

[DavidHB]

The release announcement for n-Stream version 3.0 (I think that the current version is 3.2) stated:

"This new and improved control app offers ... sorting UPnP™ lists alphabetically."

I find the published UPnP specifications quite impenetrable (and greatly admire Simon and his like for their ability to work with them), but in my understanding it is the server and not the control point that should be doing any list sorting. Also, any sort would (I think) require that the browse tree is cached in some way at the control point, which is, again in my understanding, not what the UPnP specification requires.

Is my understanding correct in these respects?
