Section 6.3.4 says:
Header: Source Used for: hierarchy Mandatory: no Inheritable: yes Repeatable: no
It should say:
Header: Source Used for: hierarchy Mandatory: no Inheritable: yes Repeatable: yes
This header is repeatable, as stated in Section 11.
However, it is currently unclear whether section 6.3.4 is correct (note use of the singular in the explanatory text) of whether section 11 is correct.
