[xsl] xsl:key (use attribute)

["David Zuccaro" <davidz@xxxxxxxxxxxxxxxxxxxxxx>]

Hello,

I have a xml file with the following structure:

<emp_enq_ap3>
	<pay_proc_nos emp_id="1" client_id="1">0</pay_proc_nos>
	<pay_proc_nos emp_id="1" client_id="1">1</pay_proc_nos>
	<pay_proc_nos emp_id="2" client_id="1">0</pay_proc_nos>
	<pay_proc_nos emp_id="2" client_id="1">1</pay_proc_nos>
	<pay_proc_nos emp_id="1" client_id="2">0</pay_proc_nos>
	<pay_proc_nos emp_id="1" client_id="2">1</pay_proc_nos>
	..............
</emp_enq_ap3>

I want to retrieve the nodeset corresponding the a given client_id and
emp_id.

<xsl:key name="emp_id" match="/emp_enq_ap3/pay_proc_nos"
use="concat(@client_id, @emp_id)"/>

Is this a correct xsl statement?

This is the error I am getting:

Expected ,, but found:
pattern = 'key('emp_id', concat(@client_id, @emp_id)'
Remaining tokens: ( ')')

Thanks in advance for your help.
