TransmissionId
An identifier for the NewsML document transmission. This should be unique among all distinct transmissions from the same publisher. If a transmission is repeated (perhaps because the sender is not confident that it was successfully received) then the same TransmissionId content may be used, but a Repeat attribute should be provided to distinguish the second transmission from the first. The form that the value of the Repeat attribute takes is determined by the provider. Likewise, the format for the TransmissionId itself is for the provider to decide. It could for example consist of a channel identifier followed by a sequence number.

| Name | Occ | Type | Description | Notes |
|---|---|---|---|---|
| Duid | [0..1] | xsd:ID | Duid is a "Document-unique Identifier". It must satisfy the rules for XML ID attributes: it must only contain name characters, and it must start with a name-start character (not a digit). Its value must be unique within any NewsML document. Every NewsML element type has Duid as an optional attribute. Combined with the Identifier element, providing a value for the Duid of any element in a NewsML document makes the element globally identifiable. The Identifier element gives global identification to the document, and the Duid provides local identification for the element within the document. | from group localid |
| Euid | [0..1] | xsd:string | Euid is an "Element-unique Identifier". Its value must be unique among elements of the same element-type and having the same parent element. Use of Euid attribute makes it possible to identify any NewsML element within the context of its local branch of the NewsML document tree. This makes it possible to copy, or include by reference, subtrees into new combinations in ways that would break the uniqueness of Duids (thereby forcing new Duids to be allocated), but still being able to retain the identity of each element. If Euids are maintained at every level, it is possible to identify, for example "The ContentItem whose Euid is abc within the NewsComponent whose Euid is def". Such identification patterns would be preserved even after "pruning and grafting" of subtrees. | from group localid |
| Repeat | [0..1] | xsd:string |
