Lars Marius Garshol will say : "the text is important, not the UML =
diagram".
;o)
But, for me, diagrams are so important : they allow me to understand =
some
time a text which is to complex without such a diagram. Sometimes, they
provide information that is not in the text.

Let's take the TopicMap overview diagram (3.3 The topic map item). It =
shows
a relation between Association and TopicMap, with a black diamond on
Association's side. In UML, for me, that says if I suppress all the
instances of the class Association, I suppress automatically the object
witch is an instance of the class TopicMap. In this way, it doesn't =
make
sense for me.
The black diamond should be on the other side!

Does it make sense? Same remark with other objects on the same diagram.
