Cannot get indexFormat to do anything

[simoncn]

displayFormat is used to produce a single formatted display value for the control point that combines multiple values for a tag (for example, multiple artists on a track or album) together with any other information that is specified in the format string. For almost all control points, this is the right way for MinimServer to handle multiple values for a tag.

multiTag is used to send multiple values for a tag to the control point without combining these values or performing any other formatting. The expectation is that all formatting, processing or combining of these values will be performed by the control point. There are only a small number of control points that are able to handle this.

As these options treat multiple values for a tag in different ways, they are mutually exclusive.
