Subject: [XSLT 2.0] Checking that an element's value has the desired datatype?

Hi Folks,
Below is an XML document containing information about the Altitude of
an Aircraft.
I have written a stylesheet to check the Altitude's value, to see if it
is an integer. Below is my stylesheet.
My stylesheet uses this statement:
<xsl:value-of select="data(flt:Aircraft/flt:Altitude) instance of
xsd:integer"/>
The output I get is: "false"
(The output I seek is "true", as the Altitude element does have an
integer value.)
Can someone tell me the correct way to do this?
Thanks! /Roger
