can't just output Standard as <p>, or anything else, because we
have structures like:
this is text <branch>and more text</branch> and more
which would then come out as:
<p>this is text <p>and more text</p> and more</p>
So we use the OutputParam html_in_par to try to signal when we
are already in a paragraph. It is expected that we will need to
do some bug fixing here.
