Hmm, is more than one copy of the same key valid?
yes
And how is that meant to be interpreted?
In the form that they all apply. "9 is a stream with translated lyrics"
I meant more broadly than just disposition.
I'm not necessarily opposed to the idea but I don't think it's well-specified at this point and I'd like to consider all the implications...
Well its intuitively meaningfull ... multiple authors
Yes, but probably in all other containers it's a single Author key with a value such as "Michael Niedermayer, Rich Felker, ..." This could also apply to disposition, but potentially makes using it harder for applications since they need to parse a sort of string list rather than just matching exact strings. On the other hand, multiple values for the same key likely does not fit well with an expected API of being able to query a key and get a value as the result.
multiple titles
Do we need meta-metainfo, i.e. language tags on the titles? :( Perhaps keys named Title-xxx where xxx is a language code? Rich
