> Very briefly, all the functions in your example are typeless. Not sure what you mean by typeless in this context? The actual examples certainly have holes in them, it was just some very late night doodling in response to you "how" question:-) But I'm not sure that you ever _have_ to save data in xslt2 as element content do you (which is I think where you are losing type information) unless you need to serialise to an XML output. If you can hold the data in memory as XPath sequences, you should be able to retain type information? Oh do you mean you need to define separate functions for separate types rather than rely, as I did, on the inbuilt polymorphism of the build in F&O functions and operators? In that case yes you do need to get type information but in that case it's not to do with the requirments of partial function application, just getting round the limitation that XPath2 signatures for user-functions have to be distinguished by arity not type.
