* for, and a series of tag-length-value stats information elements.
* The tag-length header for each stats info element also includes a
* status field, to indicate whether the request for the stat type in
* question was fully met, partially met, unable to be met, or invalid
* (if the stat type in question is disabled in the target).
* A special value of all 1's in this status field is used to indicate
