Official rule text
[BR-TMP-5] BT-125 "Attached document" (ram:AttachmentBinaryObject) may occur at most once within "Additional Supporting documents" (BG-24).
Official text (German): BT-125 "Attached document" (ram:AttachmentBinaryObject) darf innerhalb von "Additional Supporting documents" (BG-24) höchstens einmal vorkommen.
Why this error occurs
The element or combination is not allowed in this context. The file contains something the standard forbids: an element that must not be repeated, a value that contradicts another field, or data that belongs to a different profile.
How to fix it
Remove the offending element or make the two fields consistent as described in the rule text. If your software adds the element automatically, check for a profile setting (e.g. "EN 16931" vs "EXTENDED") or an export option that suppresses it.
