[Playlist] [rfc] Nested playlists (and playlist chains) again

[Sebastian Pipping]

The more I think about this nested playlists will get
us into hell A if we go that way and hell B if we go
the other. I think the driver behind this being requested
over and over (including me) is the desire to put
a whole database into one single file. The question is
how far that can and should go: When we want to
store several playlists with e.g. their own <title>s
things start to get really messy. Should we push that
into extensions? Should we put a whole <playlist> into
an extension tag? Will parsers be able to deal with
this in a reasonable use/cost ratio? I don't think so.


So maybe the best thing to do is decide to not support
nested playlists. XSPFv0/1 was not designed for this
and if a tree structure is needed it can still be handle
one layer above XSPF - in the application logic.

Nevertheless we should think about linking to external
XSPF files from within XSPF and define what's good practice
and what's not. Or is that clear already?

Please throw any thoughts on me now! If you feel your thoughts
are already made for the FAQ entry [1] please go ahead
and point us to it.
