How to access Distinguished fields and Promoted properties in BizTalk Server

Distinguished fields are accessed through a reference to the name of the message, the name of the record structure containing the distinguished field (which could include multiple levels of child records), and the name of the distinguished field, with each named item separated by periods:

MessageName.RecordName.ChildRecordName.DistinguishedFieldName.

Promoted properties, on the other hand, are accessed through a reference to the name of the message, the name of the property schema and a name of the promoted property, via the following format:

MessageName(PropertySchemaName.PromotedPropertyName).
