Doc editing help

[Chase]

I'm trying to learn my way around Confluence before I started making 
edits but I've got a question about how everything is setup.

The "Editing the Documentation" page says the content is:

Created here: http://cwiki.apache.org/confluence/display/WW/ 
<http://struts.apache.org/2.x/docs/home.html>
First copied here: http://cwiki.apache.org/WW/home.html
And then copied here: http://struts.apache.org/2.x/

However I'm seeing differences on pages that haven't been editing in a 
long time.

http://cwiki.apache.org/confluence/display/WW/Workflow+Interceptor
is different than
http://cwiki.apache.org/WW/workflow-interceptor.html

Even though the edit links on both pages go to the same page id.

The page seems to entirely comprised of snippets which I gather are 
getting pulled out of the source. Is a different set of source being 
used when rendering the live Confluence content versus when the page is 
exported to html?

When the 2.0.x docs are generated for a new release are the snippets 
coming from the 2.0 branch or the 2.1 branch?
