[GNC] AQBanking OFX DirectConnect

[John Ralls]

Interesting. USAA can't parse the OFXv2 that AQBanking 6.1.2 emits. Unfortunately it just returns an HTTP 400 response, no details. Perhaps like v1 there are Intuit-induced quirks in the v2 parser as well and we'd need to capture a v2 interaction with Quicken to figure them out.

Regards,
John Ralls
