A better example is the feature rebid by a weak 2-bid opener, because that 
bid is often on a doubleton (and could even be a stiff ace).  2H-2NT-3D 
could be made on a hand like xx KQTxxx Ax xxx, which does not have length in 
diamonds and does not want to play in diamonds.

Other bids which show stoppers are similar: 1S-2C-3C-3D is likely to be a 
diamond stopper but may not show length.

Is an ordinary cue-bid a convention if the cue-bid cannot be a void, as on 
the auction 1NT-3S-4D?  This must show the DA (or possibly the king, 
depending on your cue-bidding agreements), since the 1NT opener cannot have 
a void.
