Provides the Identifier(s) of the document being communicated.
Uniquily identifies a Document within an organization. Typically there is only an ID for
a document within one system. However, with the use of different business applications
there maybe different ids assigned to the same document within an organization from the
different systems and in the case of B2B transactions different businesses may have
different Identifiers for the same document.
This construct is designed to allow for these different identifications.
