Finally I found the matching chapter in the Dojo documentation.
So for everybody's info and completion of this thread:
You can pass parameters to topics with something like
<a onclick="dojo.event.topic.publish('documentSelected', {ID: ${ID}, Kind:
'${Kind}' }); return false">
<s:property value="Name" />
</a>
With that call you can access the properties, of the object passed to the
notified function like
dojo.event.topic.subscribe("documentSelected", function documentSelected(doc) {
dojo.io.bind({
url: "<s:url value='DocumentViewer.action'
/>?DocumentId="+doc.ID+"&DocumentType="+doc.Kind,
load: function(type, data, evt) {
var divDisplay = dojo.byId("documentContent");
divDisplay.innerHTML=data;
},
mimeType: "text/html"
});
});
Maybe that helps someone else and thanks again Musachy!
Regards
Jan

Pushing my memory to the limit: I think it is the DOM object (in this
case the anchor), that triggered the topic. You can also pass
parameters to topics, check Dojo's documentation.
