State variable test

Here's a pipeline:

<p:pipeline name="pipeline" xmlns:p="http://www.w3.org/2007/03/xproc">
<p:output port="result"/>

<p:identity>
  <p:input port="source">
    <p:inline>
      <doc episode="ERROR">
	<div for-each-position="ERROR" for-each-index="ERROR"
	     viewport-position="ERROR" viewport-index="ERROR"/>
	<div for-each-position="ERROR" for-each-index="ERROR"
	     viewport-position="ERROR" viewport-index="ERROR"/>
      </doc>
    </p:inline>
    <p:inline>
      <doc episode="ERROR">
	<div for-each-position="ERROR" for-each-index="ERROR"
	     viewport-position="ERROR" viewport-index="ERROR"/>
	<div for-each-position="ERROR" for-each-index="ERROR"
	     viewport-position="ERROR" viewport-index="ERROR"/>
      </doc>
    </p:inline>
  </p:input>
</p:identity>

<p:for-each name="loop">
  <p:output port="result"/>

  <p:string-replace>
    <p:option name="match" value="@episode"/>
    <p:option name="replace" value="$p:episode"/>
  </p:string-replace>

  <p:string-replace>
    <p:option name="match" value="@for-each-position"/>
    <p:option name="replace" value="$p:position"/>
  </p:string-replace>

  <p:string-replace>
    <p:option name="match" value="@for-each-index"/>
    <p:option name="replace" value="$p:loop_index"/>
  </p:string-replace>

  <p:viewport name="viewport" match="div">
    <p:output port="result"/>

    <p:string-replace>
      <p:option name="match" value="@viewport-position"/>
      <p:option name="replace" value="$p:position"/>
    </p:string-replace>

    <p:string-replace>
      <p:option name="match" value="@viewport-index"/>
      <p:option name="replace" value="$p:viewport_index"/>
    </p:string-replace>
  </p:viewport>
</p:for-each>

<p:wrap>
  <p:option name="name" value="wrapper"/>
</p:wrap>

</p:pipeline>

And here's the output:

<wrapper>
  <doc episode="1127bee8b26">
    <div for-each-index="1" for-each-position="1"
         viewport-index="1" viewport-position="1"/>
    <div for-each-index="1" for-each-position="1"
         viewport-index="2" viewport-position="1"/>
  </doc>
  <doc episode="1127bee8b26">
    <div for-each-index="2" for-each-position="1"
         viewport-index="1" viewport-position="1"/>
    <div for-each-index="2" for-each-position="1"
         viewport-index="2" viewport-position="1"/>
   </doc>
</wrapper>

That's the expected result, right?

                                        Be seeing you,
                                          norm
