I think 4 should read: 4) Read the document, the internal subset, the external subset, and all external entities except unparsed entities. (In my experience with Aelfred, that's what it does, though I'll admit to not actually using entities in 'real' practice.) I guess the question comes down to whether your interpretation of current practice is reason enough to combine the external subset and external entities in this situation. Given the point Sean McGrath just raised about things (INCLUDE/IGNORE, but also certain kinds of PE processing) that are legal in the external DTD subset but not in the internal subset or external PEs referenced from the internal subset, I'd say to keep these things separate. Of course, we could create a feature that simply referred to external resources, combining both properties, on top of the external PEs/external subset features. Might be the best of all worlds, though it would take some clear documentation identifying what happened if you used both the convenience feature and its sub-parts.
