I've now managed to get the P5-Pure branch of the P5 source up to date with the rest of the world, and have successfully run the P5 test suite (almost) to completion. *It would be very helpful if someone else could check this branch out and confirm that it works for them too!* The main difference is that all datatypes are now expressed using the new dataSpec and dataRef elements we discussed approx 3 million years ago. This in turn means that the old data.foo macroSpecs are now redundant, (we now use dataSpecs called teidata.foo). I have however left the old macroSpecs in the build, since their absence obviously causes existing ODDs that reference them to fall over. It's a pain however, and I would really like to get data.foo deprecated as soon as possible. Only a few (like 2 ore 3) of our test ODDs actually refer to them, but I've no way of telling how many ODDs out there in the wild do, nor how upsetting their maintainers would find it to be told to turn <rng:ref name="data.foo"/> into <dataRef key="teidata.foo"/> passim et seriatim (If you're wondering, the "(almost)" above means that my poor little laptop gave up trying to compile the massive tei_allPlus.odd.processed into tei_allPlus.rng ... probably the heat.)
