Do you mean this?

projB: svn cp trunk tags/tag1 (rev=15)

projA: svn ps svn:externals "projB file:///.../projB/tags/tag1" trunk

projB: do some work on trunk. (rev=23)
projB: svn cp trunk tags/tag2 (rev=24)

projA: svn up (rev of external = 24)
projA: svn ps svn:externals "projB file:///.../projB/tags/tag2" trunk
projA: svn up (Nothing updated since the rev hasn't changed.)

I'm not sure svn:externals is designed so that you can update the
property to another tag. Instead, you could just take note of the
revision tag1 is created and do this:

projA: svn ps svn:externals "projB -r 15 file:///.../projB/trunk" trunk
[...]
projA: svn ps svn:externals "projB -r 24 file:///.../projB/trunk" trunk

But I've never used svn:externals, so I could be wrong :)

BTW, the "foo/bar -r 1234 http://example.com/repos/zag" syntax for
svn:externals doesn't seem to be mentioned in the book. It is in the
output of "svn help propset" though.
