This document specifies the extensions to the MSDTC Connection Manager: OleTx Transaction Protocol [MS-DTCO] to support XA-compliant software components, as specified in [XOPEN-DTP], in an OleTx distributed transaction processing environment. It specifies the syntax and semantics of the new protocol messages. The document builds upon and relies heavily upon the MSDTC Connection Manager: OleTx Transaction Protocol specification [MS-DTCO], and readers must be familiar with its terms and concepts.
Sections 1.8, 2, and 3 of this specification are normative and can contain the terms MAY, SHOULD, MUST, MUST NOT, and SHOULD NOT as defined in RFC 2119. Sections 1.5 and 1.9 are also normative but cannot contain those terms. All other sections and examples in this specification are informative.
