Thanks very much for your help.
A few other questions/comments ...
> To remove items from the resource files you should just delete their content rather than commenting them out.
Sorry to be dense, but I'm not sure what you mean by "the resource files".
Do you mean the files named xxx_content.xml in the "content" folders, or
do you mean the files named xxx.xsl in the "transforms" folders ?

I guess that's what I did -- I commented out some "include item" calls in utilities_reference.xsl,
and that seemed to work. But your first approach makes more sense to me. I'll give it a try.
> you can encode special characters such as the copyright symbol using an escaped hex value (i.e. (c) = \xA9).
Actually, the copyright character worked without any escaping, but the escaping trick will be
invaluable for other things.
I feel bad asking such basic questions. Is there somewhere I should have found this information
for myself ? I did look, but was not successful.
