Ah, this makes sense to me now. I agree that, since can set and retrieve the
label information via properties, it is OK to state that the label *header*
is in one (and only one) fixed encoding, and doesn't need a language or
encoding tag.  All you need to do is compare Unicode string values for exact
equality. The ability to set and retrieve this with full encoding and
language tagging information via the property mechanism makes all the

Now that I get it, sorry for all the fuss I raised. :-(

*sigh* OK.
