BR-TMP-5

Within one supporting document (BG-24) there may be at most one embedded attachment (BT-125). Two files in the same group are not allowed, even though the schema technically permits them.

Official rule text

BT-125 "Attached document" (ram:AttachmentBinaryObject) darf innerhalb von "Additional Supporting documents" (BG-24) höchstens einmal vorkommen.

Why does BR-TMP-5 happen?

The same cause as BR-TMP-4: several attachments written into a single group. Since each group carries only one description and one document type, the recipient loses the link between file and description.

How do you fix BR-TMP-5?

Emit one ram:AdditionalReferencedDocument group per file, each with exactly one ram:AttachmentBinaryObject including its mimeCode and filename. This rule stands in for CII-SR-476, which CEN 1.3.16 binds to the wrong rule context.
