Now I *really* want two kinds of parameters:

  <p:load x:tidy="true">
     <p:param name="href" value="http://www.google.com/"/>
  </p:load>

Consider

 <p:step name="xslt">
    <p:input port="stylesheet" href="foo.xsl"/>
    <p:param name="href" value="http://www.google.com/"/>
    <p:param name="x:tidy" value="true"/>
 </p:step>

Does the presence of x:tidy on this component signal some magic
behavior? Does it mean that if foo.xsl produces HTML it'll be tidied
into XHTML? How can any processor know that it's encountering an
extension attribute. What if I don't want any extension behavior but I
want the x:tidy parameter of the foo.xsl stylesheet to have the value
"true"?

At least with

 <p:xslt x:tidy="true">
    <p:input port="stylesheet" href="foo.xsl"/>
    <p:param name="href" value="http://www.google.com/"/>
 </p:step>

My processor can know that the author was attempting to indicate some
extended behavior.
