(PowerShell) Create IRS MeF Login Service Request MessageThis 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.
