I can usually reverse-engineer things like this, but it's a little strange with cross-references. When I export, the destination is not present in the tagged text file. The Hyperlink is there, but it appears to create an "index" of where the link should go. It looks like it is based on character count, which is not practical to use when building the tagged text file.
My solution will be to output some in-line "codes" for both sides of the links, and then use scripting to build the cross-references. Thank you for the reply Peter.
