[Seaside] adding rss to head of html

[Peter Osburg]

hey guys,

i tried to play a little bit with seaside and rss stuff. so now i developed
a tool that can create valid xml output with rss content.
so what will be my next step?
i want to add the following to the head of the html:

<link rel="alternate" type="application/rss+xml" title="RSS" href="blub" />

so i decided to use the updateRoot method. but how to add the link? i tried
to use the addHeadElement and then to add a WALinkElement

updateRoot: aHtmlRoot
    aHtmlRoot addHeadElement: ((WALinkElement new) beRss)

but then i fail with an error because WALinkElement has an instance variable
called attributes that is nil. so i tried to set the attributes manually ...
to shorten the story: i failed again :)

so how can i add the tag with the "application/rss+xml" stuff to the head?
any help would be great. thx alot mates
