/* GoogleSiteMap_XML Snippet for MODx
Michal Till
`->Based on Ryan Nutt's Google Sitemap snippet for Etomite
`->Based on the ListSiteMap snippet by JaredDC
USAGE
=====
Use &allowedtemplates to specify templates, that would be included in the sitemap listing. SEPARATE BY COMMA. Don't forget to switch mime type to text/xml. NOTE: &allowed templates may be case sensitive!
ALERT: Change the website root url in the code! (will be solved in future versions)
EXAMPLE
=======
[[GoogleSiteMap_XML? &allowedtemplates=`Site,Article,Homepage`]]
