I have never run into that problem with sgml2xml/osx, but for
dealing with the issue of preventing entities from getting
expanded, I wrote a simple Perl script, called "cloak", that
hides/unhides entities (and some other things).

I run it as a pre-processing step to feeding the docs to other
tools, so that entities in them end up being hidden to the eyes of
any XML/SGML parser looking at the docs.  I then run it again as a
post-processing step, to unhide the entities and other things that
it has "cloaked".

I have put a copy of the script is here:

  http://docbook.sourceforge.net/outgoing/cloak

And I have also now checked it into the "contrib" area of the
DocBook project CVS repository. So you may also be able to get it
from the project ViewCVS interface:

  http://cvs.sourceforge.net/viewcvs.py/docbook/contrib/tools/

But that lags behind the real CVS repository by several hours. So
it may not yet be there by the time you look.
