SD wants to double check the 1790s XML data. So, I made a new version of the 1790s XML file, 1790-1799_new_structure.xml, to take into account the changes SD and I made to the XML structure. I used the 8_to_9_SD_changes.xsl stylesheet for the transformation (the same one I used for the 1800s data). The data may have to be re-imported into the MySQL database; not too sure yet.
