eb:MessageInfo

Identification and correlation block of an ebMS 3.0 message.

Definition

eb:MessageInfo, the first child of eb:UserMessage (and present in eb:SignalMessage), contains eb:Timestamp (UTC creation time), eb:MessageId (a unique RFC 2822 Message-ID) and the optional eb:RefToMessageId referencing the original message — this link is what ties a Receipt back to its UserMessage and underpins duplicate detection.

Origin

Defined in section 5.2.2.1 of the OASIS Standard ebXML Messaging Services 3.0 Part 1: Core Features, OASIS, October 2007.

Example in context

<eb:MessageInfo><eb:Timestamp>2026-06-20T10:00:00Z</eb:Timestamp><eb:MessageId>uuid-1234@sender.example</eb:MessageId></eb:MessageInfo>
