Question about documentation to DB2 UDB 8.1

FixPack for the DB2 UDB server 8.1 and FixPack for documentation for
8.1 quit in a parallel way (that is if there is FPx for the server that
should be and FPx for documentation) or they quit is not dependent from
each other ?
And that of FP3 for the server already has quitted, and FP3 for
documentation is not present.
