How do you pass step options to p:data/@href???

In the following step declaration I'm attempting to invoke HTML-Tidy:


<p:declare-step type="tidy:html">
  <p:documentation>
    <xhtml:p><xhtml:a href="http://www.w3.org/People/Raggett/tidy/">HTML
Tidy</xhtml:a></xhtml:p>
  </p:documentation>
  <p:input port="source"/>
  <p:output port="result"/>
  
  <p:option name="href"/>
  
  <p:exec command="tidy"
      source-is-xml="false"
      result-is-xml="false"
      wrap-result-lines="false"
      method="xml">
    <p:input port="source">
      <p:data href="../data/BrowseProjects.jspa.html"/>
    </p:input>
    <p:with-option name="args" select="'--quiet yes --show-warnings no
--doctype omit --numeric-entities yes --output-xml yes'"/>
  </p:exec>
  
  <p:unescape-markup/>
  
  <p:unwrap match="c:result"/> 
  
</p:declare-step>


It works fine as it is, but, I'd like to use the 'href' option I've
declared for the step to pass in the location of the source HTML file.
However, the value of: p:data/@href won't take an expression e.g. $href
and p:data doesn't allow <p:with-option name="href" select="$href"/>

How do I pass the HTML source document URI to p:data as there is no
other mechanism to get hold of unparsed character data?
