[Playlist] DTD for XSPF

[Hans Engel]

No, I have not yet done so, but I will right now. Here are the results,
checked with xmlstarlet and my DTD:

!1 - The inflexibility of DTDs has caused an error with this file,
because of the element <track> used inside the extension. <track> is
declared elsewhere, and it's confusing the parser.

!2 - Again, the inflexibility of DTDs are causing the problem here. I'll
try to figure out a way around this.

!3 - This one is my fault; I didn't pause to think that the elements
could be put in any random order.

!4 - I did not add the "xmlns" attribute to every element.

Hm, well that really proved how bad DTDs are. I will fix with the DTD
what I can, but most of the problems here are due to the inflexibility
of the DTD format.. RNG is just better overall. I suppose that's why I'm
the first to make this DTD.
