I am trying to send a request to the IRS's BulkRequestTransmitter service. I am constructing the message manually using C# (not WCF, I'm just creating all of the XML). The XML I've constructed is valid, and I can sign it with an X509 certificate (so I am past the point of the WS-Security error that many people struggle with for this service). I am also able to apply gzip compression to the outgoing request, and as far as I can tell, I am attaching the BulkExchangeFile properly. While working on this, I have occasionally seen errors telling me to ensure that the message is MTOM-encoded, but I have applied the appropriate headers and separators as far as I can tell, and the error message I currently receive is:
The message was not formatted properly and/or cannot be interpreted. Please review the XML standards outlined in Section 3 of the AIR Submission Composition and Reference Guide located at https://www.irs.gov/for-Tax-Pros/Software-Developers/Information-Returns/Affordable-Care-Act-Information-Return-AIR-Program, correct any issues, and try again.
A redacted version of my complete (uncompressed) request is below. Can anyone identify what is lacking here? Or if you have an example of a working request, would you please provide it?

Your BulkExchangeFile element isn't correct. Should look more like:
<BulkExchangeFile xmlns="urn:us:gov:treasury:irs:common">
<xop:Include href="cid:UZE_26123_" xmlns:xop="http://www.w3.org/2004/08/xop/include" />
</BulkExchangeFile>
And then the MIME header for your attachment also needs a new header to match the href in the Include element:
Content-Id: <UZE_26123_>
Use whatever identifiers you want, of course.
Source: https://www.w3.org/TR/SOAP-attachments
ctrl+f for "content-id" to see example.
