<p class=MsoNormal>What bothers me is the “Parser” template, which
seems trivial. It’s there because I needed to set a conditional “node”
variable, and the only way I could think to do it was to pass it as a parameter.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I thought about putting the “node” definition in
the st2 definition, but then I am repeating it all over the place. <o:p></o:p></p>
