* pageId1:group1,group2|groupId2:group3|c:group1,group4,groupN

* Each page element is composed by the page ID of the page setting frontend
* user access restrictions, a colon, and a comma separated list of frontend
* user group IDs restricting access to the page.
* The content access element does not have a page ID, instead it replaces
* the ID by a lower case C.
