Hi

I was just creating a Google sitemap, based on your RSS Feed example and these specs:
https://www.google.com/webmasters/tools/docs/en/protocol.html#sitemapXMLFormat

There are two optional information in the Sitemap specs: change frequency and priority.

I was thinking it could be nice to have the possibility to add these two fields in the Meta data tab of the CMS property section.

Even if these values are optional, it could provide a helpful instrument for being better indexed by Google.

As usual, the value should be defined site-wide and then for each page the value could be overwritten when the content is supposed to change more often or for important pages.

Thanks
