The next step in getting procmod into the Guidelines ought to be to produce some test files. However, as James mentioned earlier, this is not entirely straightforward. I can dream up sample ODDs which include <model> elements no problem, and can then validate them against the schemas generated from the current source. I can also re-use the ones in the Polygon directory in the original tei-simple repo, written by Magdalena. (why is it called "Polygon" btw?) However, should we not also be producing a test implementation or two showing the actual output generated with the aid of those models? That would require adding, presumably into the Stylesheets tree, some version of Magda's pilot version of a stylesheet for transforming <model>s into XSL. Or is that already there somewhere? Or are we just planning to keep quiet about the whole thing?
