I've made a bit more progress on the "processing model" extensions to ODD proposed by the TEI Simpletons a while ago, and now have a version of P5 based on the current dev branch which includes them AND builds correctly. But I havent yet finished hacking the prose into shape, and I have some questions. Here's the first. The @output attribute "the intended output method" (that's clearly wrong though; surely it should be "the intended output target"?) is defined with a closed list of values "web", "print", and "plaintext". a) why is this a closed list? I can think of lots of other possible values e.g. "mobile device", "PDF", "text-to-speech synthesizer" for starters... b) what exactly does "plaintext" mean? And here's the zero'th. To whom if not the Council should I be addressing this query?
