It is not too difficult to predict that typing will be a headache for many people for XQuery and XSLT2. Please do anything and everything that you can to reduce the problems. The different concepts around types, the different types, the different rules for conversion,... will make typing very difficult to use. It would be very good to have some section (maybe an appendix) summarizing all the rules, and giving people a chance to get an overall grasp. Giving parallels e.g. to well-known programming languages (if and where they exist) may also help. Another issue is that it is not completely predictable, and not completely interoperable, which XML Schemas will be taken into account and which not. XQuery Schema Import does a lot to make this more predictable, but this should be completely predictable. 'augmentable by implementation' does not lead to interoperability. A typical example of this is the "implementation-dependent mechanism for determining whether an unknown type is compatible..." in 2.4.4 of XPath. Regards, Martin.
