Track information in control point.

[simoncn]

MinimServer does "have a hand in the game". It sends all available metadata defined by the UPnP standard to the control point so that the control point can display whatever portion of this metadata that it chooses. Also, MinimServer provides the tagFormat capability to enable the user to do significant customisation of the medatata values that MinimServer sends.

It is possible to place a newline in a tag value if your tagging program supports this. MinimServer sends any such newlines to the control point and it is up to the control point how it handles these newlines.

I think the easiest way to find out what the Naim control point does is (as you suggest) trial and error.
