bitcoin URL

[StevenS]

I'm adding bitcoin to an online shopping cart. I've generated the QR code and made it clickable.
I have a questing on the 'label' and 'message' attributes of the URL. I tried MultiBit, which seems to ignore 'message'.

The basic question is this: Since each shopping cart checkout will have a different Bitcoin address, should I use a different label for each QR code? That is, should the label include the order number, as in ...&label=Pillow%20Store%20Order%2012345 ?

Yes, include the order number because it will help people look up info on the order and stuff... Also send an email with all of the info...
