Tweaked the XSLT to handle situations in which an <rs> tag was linked through @ref to multiple <person> ids. Set up a new catalogue file and ographies.xml file for the Harper part of the project, and went through setting up transformation scenarios with KT on her system. Not sure yet whether we should be version-controlling the mvp.xpr file in which the scenarios may be stored; each of us is likely to do different things in that file, so it may be simpler just to set up new scenarios on any system which is being used for editing.
