Yes, in fact, the idea of providing multi-valued properties were to be
able to provide several thumbnails, but also several links to the same
media. This is sensible mainly with UPnP content, where servers provide
transcoding so several streams can be used.

For the case of thumbnails, as you righly say, we should provide the
sizes of the thumbnails, or clients should check themselves each of the
thumbnails to get the right one.

In the case of multiple URLs, we should also provide a description,
mime, or something like that, for each URL, so clients knows the stream
properties (codec, bitrate, ...) to select the most appropriate. In this
case, I think it makes even more sense to have this complementary
information instead of letting clients to check each of the streams, as
most servers start transcoding when you try to access the stream.
