BAID Not Supported

[sorter]

There seems to be no way to create a recurring billing profile to charge a PayPal account. For this we would need to provide a BAID parameter.

Moreover, would it make sense to include support in this library for obtaining such a BAID?

To add some more info, I'm trying to achieve the process known as "Obtaining the BAID Without Express Checkout Purchase" as described in Express Checkout for PayFlow Document Number: 200042.en_US-201306

Adding the following method to the client appears to work

def baid_set_checkout(self, setpaypal, amount, extras=[]):
    params = dict(trxtype = "A", action = "S")
    for item in [setpaypal, amount] + extras:
        params.update(item.data)
    return self._do_request(None, params)

And I use it like this:

setpaypal = SetPaypal(returnurl='https:/domain.org/paypal/baid/return',cancelurl='https://domain.org/paypal/baid/cancel')
zeroamt = Amount(amt=0.00, currency="USD")
btype = BillingType(billingtype='MerchantInitiatedBilling')
extras = [btype]
r=pclient.baid_set_checkout(setpaypal, zeroamt,extras=extras)

I wonder if I could have achieved this result without modifying the source.
