Call bpws:getVariableData from xslt

Question

Hello,
I need to access a global xml BPEL variable from my xslt script called by a ora:processXSLT function, from an assign block.
In order to have this, I tried to call “bpws:getVariableData” inside the xslt, but I receive the following error at runtime:
“Extension function http://schemas.xmlsoap.org/ws/2003/03/business-process/ : getVariableData is unknown. Please verify the xpath query.”
This is a part of the xslt file:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0"
xmlns="http://oracle.com/SimpleMerge"
                    xmlns:bpws="http://schemas.xmlsoap.org/ws/2003/03/business-process/"
xmlns:a="http://oracle.com/SimpleMerge">
<xsl:output method="xml" indent="yes" />
     <xsl:variable name="services" select="bpws:getVariableData(&quot;serviceType&quot;, &quot;payload&quot;)"/>
Any idea?
Thanks,
Ion

Thanks Eric, this has given me an idea for another little problem I was facing, so thanks.
I think what I'm interested in is passing parameters into a transform, so something along the lines of:
ora:processXSLT('MyTransform.xsl', bpws:getVariableData('inputToTransform'), 'param1', 'value1', ...)
(where additional (optional) parameters would appear in pairs.)
From my understanding, 114, is just a wrapper for an XSLT transform. In my situation, I have an existing XSLT file (that I can't modify) which takes a number of parameters. This is why I'd like to use this kind of mechansim. If I adpated 114 for my example, I would still have the problem of passing parameters into my transform.
This is all slightly off the original topic maybe, but it was raised earlier in this thread. I notice that this is something that active BPEL supports, so was wondering if there was something similar in Oracle BPEL.
