In 1.7 syntax that could be done nicer:
<mm:node number="$author">
<mm:relatednodes type="documents" role="posrel" orderby="posrel.pos"
directions="UP">
....
</mm:relatednodes>
</mm:node>
In order words, no need to use element="document" in these cases, which
looks nicer, and would be more efficient for the database too.
