Setting a Schematron 'let' variable via XProc

Hi all

I am trying to set the value of a 'let' variable in Schematron via XProc without success. Can anyone provide any hints?
My Schematron has the following defined at the top:

<let name="basedir" value="'/'" />
<let name="mappings" value="document(concat($basedir, 'xsl/mappings/controlled-vocab.xml'))" />

And I am trying to set the value of the basedir variable via the XProc task:

<p:validate-with-schematron assert-valid="false" name="intermediate-validation" phase="intermediate">
        <p:log port="report"/>
        <p:input port="schema">
            <p:document href="schematron.sch"/>
        </p:input>
        <p:with-param name="basedir" select="'foo/bar'"/>
    </p:validate-with-schematron>

But this fails to set the value, and basedir remains at its default value.

Is there a way to set Schematron variables via XProc?

Many thanks

Phil
