Indeed. But although it gives you a wider range of data types than just
strings -- it's fine for a sequence of integers or a date -- it's still
restricted. For example there's no way you can hold a function as an attribute
of an element node, because (a) functions aren't recognized as an XSD data
type, and (b) they can't be represented as strings. This lack of orthogonality
in the XDM model is a constant pain when you're doing applications like the
XSLT-in-XSLT compiler that we wrote for Saxon-JS, or the XSD-validator-in-XSLT
that I've published details of but never released as a finished product.
