/**
 * "Access Rootline", represents all pages and specifically those setting
 * frontend user group access restrictions in a page's rootline.
 *
 * The access rootline only contains pages which set frontend user access
 * restrictions and extend them to sub-pages. The format is as follows:
 *
 * pageId1:group1,group2/pageId2:group3/c:group1,group4,groupN
 *
 * The single elements of the access rootline are separated by a slash
 * character. All but the last elements represent pages, the last element
 * defines the access restrictions applied to the page's content elements
 * and records shown on the page.
 * 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.
 *
 * The groups for page elements are compared using OR, so the user needs to be
 * a member of only one of the groups listed for a page. The elements are
 * checked combined using AND, so the user must be member of at least one
 * group in each page element. However, the groups in the content access
 * element are checked using AND. So the user must be member of all the groups
 * listed in the content access element to see the document.
 *
 * An access rootline for a generic record could instead be short like this:
 *
 * r:group1,group2,groupN
 *
 * In this case the lower case R tells us that we're dealing with a record
 * like tt_news or the like. For records the groups are checked using OR
 * instead of using AND as it would be the case with content elements.
