1.8 Vendor-Extensible Fields
MSDTC Connection Manager: OleTx Transaction Protocol gives vendors the ability to provide implementation-specific protocol extensions to the Core Transaction Manager Facet section 1.3.3.3.1. This protocol provides the following vendor-extensible fields and data elements:
A protocol extension can augment the default set of transaction manager facets that are implemented inside an implementation of the transaction manager role, as specified in section 3.2.1.4. A protocol extension provides a set of services, as specified in section 3.2.1.5.
A protocol extension also includes the contribution of extended whereabouts information to the Core Transaction Manager Facet, as specified in section 3.2.3.
Each vendor-supplied transaction manager facet has the option to use the local events that are provided by the Core Transaction Manager Facet that is specified in section 3.2.7.
