Realizing I need to have more sample content in TEI, it strikes me that converting it from ISE is the simplest and most useful way to get it because I'll learn ISE stuff in the process. Started work on a transformation to do that, and completed the work on the header, which will be very useful. Working on the body, which in the current incarnation of ISE XML has a bit of a nightmare of fragmented hierarchies, I made some progress, but I'm now assured by MT that they're working on a better XML version which I should use instead. Waiting to see what that looks like.
