An MMBase relation object is then a special kind of normal object with 2
node fields, and recognized by query-objects and syntax.
<mm:list path="news;author,people"> or so which would lead to
select .. from news n, people p where n.author = p.number;
in stead of
<mm:list path="news,author,people"> which would lead to
select .. from news n, insrel i, people p where n.number = i.snumber and
i.dnumber = people.p.number and i.rnumber = ..;
Sounds nice,
it really depends on the constraints sometimes you will need an IN constraint
<mm:list path="news;author,people" constraint="people.name='keesj'">
