Here's an real-world example that doesn't contradict:
http://amarok.kde.org/wiki/Installation_HowTo#From_Anonymous_SVN
"svn co -N svn://anonsvn.kde.org/home/kde/trunk/extragear/multimedia
cd multimedia
svn co svn://anonsvn.kde.org/home/kde/branches/KDE/3.5/kde-common/admin
svn up amarok
To compile the sources (from the multimedia directory):"
and there's probably very few people that want to clone the entire KDE
multimedia sub&super-module in this case.
