DOCBOOK: link ID

[Inge <telmin@ol.telia.no>]

Hello.

I would like to learn how to make these links in (simplified) docbook xml.
i say <link linkend="foo">Foo</link>, right? 
(Or must i specify which foo an where in some way? how to do?)
And then how do i establish the reference in the point of the linkend?
if there is a paragraph or a programlisting in an example, whichever, 
what do i do to say: 
-here is the destination of that link "foo"?

i would like to learn this by example, would anyone please drop me a line (i guess i am the only subscriber to this list who can't do this basic linking..). (I can handle some constructive sarcasm....)?

Java is not my cup of tea.
