position="ALL" was removed in the latest version. This is not a bug. See the 
change log

You're right, the change log does say it has been removed. So what should be 
used now instead of "all"? The examples in the Wiki don't give an alternative. 
You've "deprecated" an option (https://code.google.com/p/vqmod/wiki/Scripting) 
by removing it, which leaves anything that relies on that functionality in the 
lurch!

position="all" you can use the following:
offset="500" : line number of file to replace
<operation info="Replace class function">
            <search position="replace" offset="500"><![CDATA[class]]></search>
<add ><![CDATA[ <!--code --> ]]></add>
