I'm sad because we are endlessly debating calling '<' and '>'
"special characters" that can't be in data set variable labels (or
not). Apparently 'lt' and 'gt' are clearer (but potentially make
the labels too long).  We've always used '<' and '>' (plain ASCII
characters) in labels and never had this issue before.
