As I get further into marking up the first text, I've begun to flesh out the documentation for encoders. I've added a new Markup instructions document, which will grow as we go along, and also made some basic changes to the Textual features page, which overlaps it a bit. I've also posted a detailed query to the TEI list about whether block items such as lists and linegroups should ever, or need ever, appear outside of paragraphs. My sense right now is that they sometimes have to be inside paragraphs, but I can't think of any situations in which they must be outside paragraphs, so I might be able to customize the schema heavily to restrict them in this way, and make life simpler for encoders.
