Right now, I suggest leaving streaminfo and metadata combined into
the same tag, and the application should assume that everything
associated with certain tags (e.g., "codec" or "length") be
considered streaminfo, and everything else be considered metadata.
That quite closely approximates what we actually want, since "length"
in an id3 tag doesn't somehow magically become metadata.
After 0.8, perhaps we should add this information to the tag registry
itself, to indicate the purpose of each tag.
(I'd be interested in knowing any tags that can be both metadata and
streaminfo. Seems like a bug to me.)
