I don't know what this is as it was not in Version 2.0 It seems
redundant. The varRef (Row 21) provides the IDREF to the variable
describing this dimension. The name of the dimension would be obtained
from the label of the referenced variable. Sorry I can't shed any more
light on this. The cohort (ability to identify a subset of the categories
of the dimension variable is a separate thing and appears to be in rows
22-30.

I'll have to go over this whole thing carefully.
