[sc34wg3] TMDM doesn't specify what is reified?

SRN mentioned this criticism of the TMDM to me at the end of the
Extreme conference: "TMDM doesn't specify what is reified and what is
not". I don't understand that at all, but he said it was the key
problem he saw with it, so I'd really like to get to the bottom of
this. Unfortunately, I don't understand what this means.

SRN, please let me try to ask you some questions, to see if we can
clarify what problem you are perceiving:

  - what does it mean for something to be reified? what is the "acid
    test," as it were?

  - how can TMDM specify or fail to specify this? again, is there a
    kind of "acid test" that can be applied?

  - is there something else you could say to help me understand this?

What I'm looking for with this discussion is to get us to a point
where we all agree the TMDM meets this requirement. The two ways of
doing that are either demonstrating that the TMDM does meet it
already, or fixing it so that it does. Either way, the first step is
to understand what it means. :)
