The survey tool is currently not using the current winning value to do error
checking, but instead is using the "old" value from the previous release.
For example http://unicode.org/cldr/apps/survey?_=ca&forum=ca&xpath=3497 reports
an error because the current winning name for code BOP "peso bolivià" conflicts
with the incorrect old name for code BOB "peso bolivià", which has been
corrected to "boliviano". Error checking should always take place against the
current winning value and not the old value.
