Re: p:store and default readable ports

I asked this question a while back and based on response from James Sulak

http://markmail.org/search/?q=list%3Axproc-dev+p%3Astore#query:list%3Axproc-dev%20p%3Astore%20from%3A%22Alex%20Muir%22+page:2+mid:ictw4wbiqi5k2bte+state:results

I use the following:

The code uses a declared step which handles the identity and then accepts a
boolean to determine if the output should be written using the passed href
parameter as the file name.

 <p:declare-step name="saveDocument" type="mh:save-output">
    <p:input port="source" primary="true"/>
    <p:output port="result">
      <p:pipe port="result" step="ident"/>
    </p:output>
    <p:option name="step-name" required="true"/>
    <p:option name="save" select="'false'"/>
    <p:option name="href" required="true"/>
    <p:identity name="ident"/>

    <p:choose>
      <p:when test="$save = 'true'">
        <p:store>
          <p:with-option name="href" select="$href">
            <p:pipe port="result" step="ident"/>
          </p:with-option>
        </p:store>
      </p:when>
      <p:otherwise>
        <p:sink/>
      </p:otherwise>
    </p:choose>
  </p:declare-step>

And use it in the code.

         <mh:save-output step-name="debug1">
            <p:with-option name="save" select="~~~debug~~~"/>
            <p:with-option name="href"
              select="concat($debug-output-
folder,'debug-1.xml')"/>
          </mh:save-output>

replace the ~~~debug~~~ with true() or false()
