Hello! First the background of my question and bug report:
I'm contributing to development of the LaTeX2rtf converter and we got requests 
from OO users to make its rtf output OO compatible.
Generally OO imports our rtf quite well but it doesn't recognize the field 
functions. LaTeX2rtf (up to now) only generates
- bookmarks
- REF fields for references to the bookmarks
- EQ fields for equations.
While we already included an option for not generating EQ fields - AFAIK OO 
doesn't have an equivalence to these -, we'd like to at least convert the 
crossreferences.
QUESTION:
How must bookmarks and crossreferences be coded in rtf to be successfully 
recognized by OO?

To solve the question, I created document with a bookmark and a crossreference 
in OO and saved as rtf, BUT THAT DIDN'T WORK. 
HERE ARE THE BUGS:

1.) The bookmark is exported but it does not contain the text it originally 
contained. E.g. if in the document I bookmark the string "abc" then the exported 
rtf code is
abc{\*\bkmkstart BookMarkName}{\*\bkmkend BookMarkName}
or
{\*\bkmkstart BookMarkName}{\*\bkmkend BookMarkName}abc
while it should be
{\*\bkmkstart BookMarkName}abc{\*\bkmkend BookMarkName}

2.) The cross reference field isn't exported at all, the rtf code just contains 
the field results.

OO itself doesn't recognize these fields which it exported to rtf.
