Is there an easy way to have it now recurse when its the same resource when 
a index.html/Overview.html is used by the Web server?

Does checklink ask for text/html and application/xhtml+xml docs? I content 
negotiate on the namespace redirect [1] so if you ask for html, that's what 
you get, if you ask for application/xml you'll get the schema and such. The 
default is the html document though, so if you're not sending any accept 
header, maybe I have a bug?

That would be useful.
