OK, Christmas is tiring: I meant @label.

However, @title is actually an attribute that we haven't determined what it's
used for in <track> and it can take any advisory information for the element.
So, if all we need is a means to map descriptive information from in-band
tracks to an IDL attribute, it may be of use?

So, for your use case, @kind would be fixed and set to the string "metadata",
@label to whatever is in Ogg's "name" field, and @title could contain a
concatenation of Ogg's "content-type" field and whatever remains of Ogg's
"role" field that is not "metadata".
