p:rename problem

Evening folks

I'm obviously doing something wrong here but I'm also obviously failing to see what. Could anyone point me in the right direction? I have the following xproc script (actually, the final stage of a much longer script but it exhibits the problem). 

<?xml version="1.0" encoding="UTF-8"?>
<p:declare-step xmlns:p="http://www.w3.org/ns/xproc" version="1.0"
    xmlns:c="http://www.w3.org/ns/xproc-step" 
    name="reset-identifiers">
    <p:input port="source"/>

    <p:output port="result">
        <p:pipe port="result" step="done"/>
    </p:output>

    <p:rename name='new-identifiers' xmlns:corbas="http://www.corbas.net/ns/functions">        
        <p:with-option name="match" select='@corbas:id'/>
        <p:with-option name="new-name" select='xml:id'/>     
    </p:rename>

    <p:identity name='done'/>

</p:declare-step>

I have the following xml doc that I'm feeding into the above (again stripped down to the minimum):

<book xmlns="http://docbook.org/ns/docbook" 
    xmlns:xlink="http://www.w3.org/1999/xlink"
    xmlns:corbas="http://www.corbas.net/ns/functions" 
    version="5.0" corbas:id="ba-9781849662505">
</book>

calabash dies with the following exception:
