We did say it. Section 5.2 Types.

Unconstrained means the TMRM doesn't know what data types you have 
defined in your Subject Map Disclosure. How could we?

You define whatever you want to do. See the viewing function under 2.1 
Maps. We don't assume they can be compared, we assume people can say if 
they want to compare them and then define how.

Hope you are having a great day!
