how do I get rid of that pesky namespace?

This input

<p:declare-step xmlns:p="http://www.w3.org/ns/xproc">
    <p:input port="source">
       <p:inline>
           <foo>Hello, world!</foo>
       </p:inline>
    </p:input>
    <p:output port="result"/>
    <p:identity/>
</p:declare-step>

Produces this output on Calabash 0.6.0.

<foo xmlns:p="http://www.w3.org/ns/xproc">Hello, world!</foo>

Something similar happens when I use p:document for an XML doc without a
namespace.

How do I get rid of that pesky XProc namespace for my output?

TIA,
