[xsl] selecting for variable based on attribute

["Rick Roen" <Rick@xxxxxxxxxxxxxxxxxx>]

XSLT 2.0

I have an xml like this snippet: 		

<items>
      <item print="1" hardware="0" packetdescription="FLOWER " sku="">
			<itemnum>3</itemnum>
			<location>687</location>
			<qty_order>5</qty_order>
			<qty_ship>5</qty_ship>
			<upc>051178000033</upc>
			<rack>1</rack>
			<tray>1</tray>
			<pocket>2</pocket>
			<name>ALYSSUM BASKET GOLD</name>
			<eta/>
			<retail>1.49</retail>
			<cost>0.708</cost>
			<total>3.54</total>
		</item>
		<item print="1" hardware="0" packetdescription="FLOWER "
sku="">
			<itemnum>4</itemnum>
			<location>686</location>
			<qty_order>5</qty_order>
			<qty_ship>5</qty_ship>
			<upc>051178000040</upc>
			<rack>1</rack>
			<tray>1</tray>
			<pocket>3</pocket>
			<name>ALYSSUM CARPET OF SNOW</name>
			<eta/>
			<retail>0.99</retail>
			<cost>0.470</cost>
			<total>2.35</total>
		</item>...
	</items>

And an xslt snippet like this:

			<xsl:variable name="rack" select="items/item[rack
castable as xs:integer and tray castable as xs:integer and pocket castable
as xs:integer and @hardware ne '0' ]"/>

This returns an empty sequence for $rack.  When I leave out the "@hardware
ne '0'" then it returns what I would expect, i.e. the items/item.

How do I test for the hardware attribute <> 0?
