Free extensions for Joomla!

i must say this is a GREAT component for my site
its a great site map
however i can not use it for google
https://www.google.com/webmasters/tools/docs/en/protocol.html
is it possible on the next update that Xmap to create XML site map link that google can use

the main reason that i am even using this component is so that google can better index my site

again this is a GREAT component
