I think you mean the second XML-file: *
That file is used to give the menu-manager the view you want to display
and, as is the subject of this article article in the series, the
helloworld-messag you want to show. The new helloworld-field is filled in
the field-definition you see in the file under it. Parsing of the parameter
in the field is done by the menu-system. The result of that field is: the
id of the helloworld-message you want to show in the view. That id is given
to the component and used by the model to choose the right message.
The first XML-file in the article, *helloworld.xml*, is only used to
install the component. During execution of the program it is not used
The installer reads it, puts the files on the right place, sets the
component in the database, performs the sql etc.
Or are you looking for some more explanation of how this so-called
'manifest' is built up and what the exact meaning of all tags is?
