BR-TMP-4

Within one supporting document (BG-24) the document description (BT-123) may appear at most once. Several names for the same attachment are not allowed — a second document needs a second BG-24 group.

Severity: Warning

Official rule text

BT-123 "Supporting document description" (ram:Name) darf innerhalb von "Additional supporting documents" (BG-24) höchstens einmal vorkommen.

Why does BR-TMP-4 happen?

This happens when several attachments are written into one group instead of one group per attachment: the loop appends ram:Name repeatedly to the same node. The recipient can then no longer tell which name belongs to which file.

How do you fix BR-TMP-4?

Emit one ram:AdditionalReferencedDocument group per attachment, each with exactly one ram:Name. This rule stands in for CII-SR-475, which CEN 1.3.16 binds to the wrong rule context so that it never fires.
