No. Why do you say that? The item may never have been near an xsd
schema.

If you have a sequence

(1,'1',true(),'true')

then a nested test with instance of will show those types as xs:integer,
xs:string, xs:boolean and xs:string respectively.

this does not depend on any internals of the XSL processor the result is
determined by the xpath spec. (I am assuming here that xs: is bound to
the xsd schema namespace)
