Exhausting set of corrections for the Osborne text, with some questions still outstanding; one issue involved th loss of spaces in listBibl/bibl entries, which proved to be caused by the use of Xalan on the server (so it didn't show up on local builds, where I use Saxon). I edited the sitemap.xmap file for ScanCan so that it calls Saxon instead of the default "xslt" (=xalan), and the problem seems to be solved.
