As far as I understand the spec and Mozilla's implementation the label
has no semantics for the browser. You can set it to any value you like
and it's your responsibility as developer to make the DCs
distinguishable from each other.

IMHO it would help to include an example use case for the "label" and
"protocol" fields in the spec.
