Don't know who to thank but, I inserted xml:lang="la" as follows:
<set xmlns="http://docbook.org/ns/docbook"; xmlns:xi="http://www.w3.org/2001/XInclude"; xmlns:xlink="http://www.w3.org/1999/xlink"; version="5.0" xml:lang="la"> obviously Latin text, and voila, the spelling of the text checks out. Amazing! Thanks to whoever! Paul
