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

Norm was being a little casual.  Here's the fully-articulated version
based using p:http-request, resulting in exactly the signature I
believe you want for my:tidy:

  <p:pipeline xmlns:p="http://www.w3.org/ns/xproc"
              xmlns:c="http://www.w3.org/ns/xproc-step"
              xmlns:my="http://www.ltg.ed.ac.uk/~ht/"> 

   <p:declare-step type="my:tidy">  
    <p:output port="result"/>
    <p:option name="uri" required="true"/>
    <p:add-attribute match="c:request" attribute-name="href">
     <p:with-option name="attribute-value" select="$uri">
      <p:empty/>
     </p:with-option>
     <p:input port="source">
      <p:inline>
       <c:request override-content-type="text/plain" method="GET"/>
      </p:inline>
     </p:input>
    </p:add-attribute>
    <p:http-request/>
    <p:exec command="tidy" source-is-xml="false" result-is-xml="true"
            wrap-result-lines="false"> 
     <p:with-option name="args" select="'-asxml --quiet yes --show-warnings no
 --doctype omit --numeric-entities yes --output-xml yes'"/> 
    </p:exec> 
    <p:unwrap match="c:result"/>
   </p:declare-step>  

   <my:tidy uri="http://www.ltg.ed.ac.uk/~ht/xx.html"/>

  </p:pipeline>

That add-attribute+http-request idiom is my candidate for pulling out
as a declared step in a common library.
