File externals before subversion 1.6

It seems, in one of our repositories, that Someone(TM) has been
using svn:externals to include single files.  This was done with
version 1.4 of the SVN server, and it seems to have worked, even
though I thought single file externals was first implemented for
server version 1.6.  How can this be?

With kind regards
