XATMGUID (16 bytes): This field MUST contain a GUID that specifies the XA Transaction Manager Identifier for the XA Transaction Manager instance.
RMGUID (16 bytes): This field MUST contain a GUID that specifies the Resource Manager Identifier for the XA Transaction Manager instance.
BranchGUID (16 bytes): This field MAY contain a GUID initialized by the AP that specifies the XA Branch Identifier for this branch. Whether the AP specifies this or not is implementation-specific. The BranchGUID is not used by DTC; however, the bqualLength field in the XA_XID structure MUST be specified accordingly as in section 2.2.1.3.
