SGML and HTML

At URL http://postgresql.nextpath.com/docs/user/operators2533.htm, we
are showing some entries like:

%gt;=               Greater or equal                                                '192.168.1.5'::inet >=
'192.168.1.5'::inet%gt;               Greater                     '192.168.1.5'::inet%gt; '192.168.1.4'::inet
 

These should be >=, I believe.  The SGML source shows:
   <ENTRY> <= </ENTRY>   <ENTRY>Less than or equal</ENTRY>
So somehow in the conversion, the & is being converted to %.  Any ideas
why?
