Many thanks to Kevin Grover for pointing out the following correction:
Page 33, Section 3.4.2 "Setting up Access"
These URLs:
http://svn.example.com/srv/svnrepositories/repos_uno
and
http://svn.example.com/srv/svnrepositories/repos_dos
SHOULD BE
http://svn.example.com/repos/repos_uno
and
http://svn.example.com/repos/repos_dos
to be consistent with the httpd.conf snippet.
