I now have a process that builds an encoder package, which contains:

• XML files and related images harvested based on the XML file facsimiles
• CSS for readable display of the XML, and clickable links to image files (needs a fix; I'm using a Unicode char to represent images which only works on Linux)
• Latest schema with all taxonomies included
• An instructions document with read-only Author Mode display
• An ant task associated with the instructions doc which will build a zip file either of the XML only or of the whole project, for easy portability/return of edited files to administrator

Tested and working on Linux, Windows and Mac. Only remaining tasks:

• Replace the page-image char with something more widely supported (perhaps an icon)
• Complete the instructions, with Gord, and make them easily navigable through a hyperlinked TOC.
