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) David ________________________________________________________________________ The Numerical Algorithms Group Ltd is a company registered in England and Wales with company number 1249803.
