You can use the instance of and typeswitch expressions to inspect the
type.

 

Exposing the type name is a feature of the debugger in my opinion and
not a language feature.

Subject: [XSLT 2.0] Is it possible to display the type of a node / value
/ variable?

 

Having spent a great deal of time today trying to work out where a
typing problem was going wrong (my coding, Saxon 7.5 support of what I
wanted to do, etc) I would really have liked to be able to display the
type of (in my case) a variable at various points in the code - in order
to see what was and what wasn't working.

Is there a function to do that? As far as I can see the data() function
which is said to return the "typed value" doesn't actually return the
type, at least not in a form that I could serialize, which I would need
to do in this debugging scenario.

If not, it seems to me that a function to display the type of a node, an
atomic value and a variable would be useful for debugging XSLT 2.0
stylesheets as people grapple with the "interesting" aspects of typing
in XSLT 2.0 not behaving quite as expected.
