Description

I did a following xquery assign:

<assign name="assign1">
<copy>
<from expressionLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xquery1.0">
<![CDATA[
for $loopOnce in (1)
return
<test:test1>
<test:test2>abc</test:test2>
</test:test1>
]]>
</from>
<to variable="myVar" part="TestPart"/>
</copy>
</assign>

and run it in servicemix.
I got:

I noticed that this example run successfully in ODE tests. I saw that a difference is that evaluated node list is of Xerces DOM impl in ODE tests, and Saxon DOM impl in Servicemix.
