I don't think the message is currently stored in the Satoshi client.
That feature is somewhere on our way-too-long issue and todo list.
But I understand that you want to add transaction meta-data fields
such as contact information, bought items, item prices?
I don't want to add fields to the URI-spec, I just want to add them /to
the client/. To me, it is ideal to have separate strings for labeling
/addresses/ vs labeling /transactions/ -- i.e. different strings would
show up in the address book (owner info) than what shows up in the
transaction history (purchase info). I say it's ideal because that
concept seems to fit perfectly with availability of "label=" and
"message=" fields in BIP 21, but it won't actually work if Bitcoin-Qt
won't/can't do it that way.
For now, it seems that I should count on all important information being
in the /label/ field, since users creating URLs would have to assume
anything in the /message/ field will not be saved. Though I imagine the
message data will be /displayed/ after the URI is clicked, just not saved.
To expand the concept slightly further, it might make sense in the
future for users to populate the /message/ and /label /fields with lots
of data, using newlines. The first line would be used as a summary and
displayed in the address book and ledger. The extra lines would all be
displayed when the user opens up a details window. All of it would be
automatically generated by the merchant, and the purchaser would end up
with detailed documentation on every purchase they've made for zero effort.
