Tags and branches can look very similar in CVS if you aren't careful. 
3-1-RELEASE is a tag for the actual revisions in the formal release of 3.1. 
At this point the netbsd-3-1 branch was branched. There isn't a 
netbsd-3-1-base tag.

Take a look at the following for example:
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/sys/param.h
Look at rev 1.211 and then all subsequent commits against that branch (which 
all begin with 1.211.). 1.211.2.14 is the actual version in the 3.1 release, 
there are later commits to that branch (which all begin with 1.211.2.14.).
