site definitions

[johnyperu]

I want to alter the top nav bar in my site definition.
msdn quotes as:

NavBars Element
The NavBars element contains definitions for the top navigation area that is displayed on the home page or in list views, and definitions for the side navigation area that is displayed on the home page.but when I look in the sts sites's onet.xml it has the navbar element as a load of gunk as below

Name="$Resources:core,category_Top;"
Separator="   "
Body="<a ID='onettopnavbar#LABEL_ID#' href='#URL#' accesskey='J'>#LABEL#</a>"
ID="1002" />

how can i edit this stuff as its all programmaticly built by the looks of it ?

any clues??

thanks
