[xsl] Working with QNames in strings in XSLT 2.0

[Ian Stokes-Rees <ijstokes@xxxxxxxxxxxx>]

Hi,

I'm trying to work with the XSLT 2.0 functions for manipulating QNames, 
but am at a loss for how to check QName strings in XSLT.  I am using 
Saxon-B 9.1.0.

I will have input documents of the form:

customer1.xml:
<foo xmlns:a="urn:item-namespace-1.0" mode="a:blip" value="ping"/>

customer2.xml:
<foo xmlns:b="urn:item-namespace-1.0" mode="b:blip" value="pong"/>

I want to write a template which will match the <foo> elements with 
@mode attributes set to the QName of {'urn:item-namespace-1.0','blip'}, 
however using a NS prefix taken from the document.  I can't figure out 
how to do this.  My best guess (which doesn't work) is:

<xsl:template match="foo[resolve-QName(@mode,.) = 
QName('urn:item-namespace-1.0','blip')]">
   <bar value="{./@value}">found element foo with right mode</bar>
</xsl:template>

I've searched the archives, the FAQ, the XSD and XSLT specs, and some 
other XSLT 2.0 function references but to no avail.  Any suggestions 
warmly welcomed.

Ian
