Sure, "with-option" is just a dynamically evaluated form of putting
the options as attributes on the step tag.
I.e.
  p:insert match="Structure"
should be the same as
  p:insert
    p:with-option name="match" select="'Structure'"
The difference is that the value of a "with-option" is a dynamic XPath
expression, so you have to quote it as a string if you just want
something static.
