The current first paragraph of section 5.1.5 says this:

"For interchange between programs, the dimensions presented in this specification MUST NOT be converted to another system of units but MUST remain as defined in this specification."

This is lacking a statement from MSN1 about duplicate sizes. The first paragraph should say something like this:

"For interchange between programs, the dimensions presented in this specification MUST NOT be converted to another system of units but MUST remain as defined in this specification. Furthermore, an identical size with different units MUST NOT be registered in the IANA Registry. Programs may convert the dimensions to other units when displaying these names to human users and for internal use, both of which are outside the scope of this specification."
