Michael,

In other words, to be able to use date / time / duration related functions a newcomer to XSLT 2.0 will need to learn how to write correct (lexical forms of) types such as xsd:date, xdt:yearMonthDuration and so on. I don't see that as an onerous burden. But I can't see how that minor acquisition of new information can be avoided either, except if the stylesheet author chooses to continue to use string-related functions to manipulate dates (as has been the case in XSLT 1.0).

With a Basic XSLT Processor (i.e. one that does not support schema
validation), the nodes in a source document will always be untyped.

Is that correct?


As I read XSLT 2.0 (Section 21.1) element nodes processed by a Basic Processor are annotated with xsd:anyType and attribute nodes with xdt:untypedAtomic. So those nodes are typed, but in such a way as to leave pretty open how they can be used.

I would have expressed it as nodes in a source document will always be typed (as xsd:anyType or xdt:untypedAtomic in the case of a Basic XSLT 2.0 Processor) but they can be used as if they were untyped, assuming they meet the not very onerous lexical constraints.
