Issue-233

*Normative:*

Data retained by a party for permitted uses MUST be [replace "limited" with
minimized] to the data reasonably necessary for such permitted uses.  Such
data MUST NOT be retained any longer than is [replace proporationate with
proportionate] and reasonably necessary for such permitted uses.

*Justification:*

The term “limit” suggests a hard boundary whereas “minimize” suggests a
more flexible boundary that can be lowered as appropriate to provide
privacy gains.

In other words these terms operate in different directions.  Limit is a cap
and minimize provides pressure to decrease, which is better for privacy
gains.
