Create IRS MeF Login Service Request Message
See more XML Digital Signatures Examples
This example demonstrates how to create a digitally signed Login Service Request Message.This example used the documentation at https://www.irs.gov/pub/irs-utl/mef-doc-stp_ref_guide.pdf as a guide.
It creates signed XML as specified in section 4.1.1 found in Section 4: Example A2A Web Service Messages.
