Are the expected results for this test correct?

The keys are:

 <xsl:key name="k" match="item" use="."/> (from XSLT 1.0 stylesheet)
 <xsl:key name="k" match="item" use="number(.)"/> (from XSLT 2.0 stylesheet)

The input number is:

<content>
 <data>
  <item>1.00</item>
  <item>2.00</item> 
  <item>1</item>  
  <item>2</item> 
 </data>
</content>

Both will use backwards-compatbility behaviour, due to one key being from an XSLT 1.0 stylesheet.

key('k', 1.0) will return:

 <item>1.00</item> because number(<item>1.00</item>) cast as string = 
                           number(1.0) cast as string

and

  <item>1</item>  because number(<item>1</item>) cast as string = 
                           number(1.0) cast as string

Have I missed something?
