A column can be tagged with a custom tag. In this case, the user must
indicate an auxiliary table that contains statistical information on
the possible values of this column (below).
A column can be tagged with a InfoType to use the relevant public
dataset as a statistical model of population, if available. We
currently support US ZIP codes, region codes, ages and genders.
To programmatically obtain the list of supported InfoTypes, use
ListInfoTypes with the supported_by=RISK_ANALYSIS filter.
