+1, with "and MUST have a PID parameter with the same value".

The PID parameter is useful in case you have this:

TITLE;LANGUAGE=fr:Directeur de la recherche
TITLE;LANGUAGE=en:Director of Research
TITLE;LANGUAGE=fr:Président, groupe de travail vCardDAV
TITLE;LANGUAGE=en:Chair, vCardDAV working group

Here you can't reliably know which one goes with which without the PID
parameter. Better:

TITLE;LANGUAGE=fr;PID=1:Directeur de la recherche
TITLE;LANGUAGE=en;PID=1:Director of Research
TITLE;LANGUAGE=fr;PID=2:Président, groupe de travail vCardDAV
TITLE;LANGUAGE=en;PID=2:Chair, vCardDAV working group
