1252      *
1253      * - Splitting $this->id if it contains an additional type parameter.
1254      * - Getting the id for an alias in $this->id
1255      * - Finding the domain record start page
1256      * - First visible page
1257      * - Relocating the id below the domain record if outside

1260      *
1261      * - id

1264      * - domainStartPage
1265      * - sys_page

1284      * @todo:
1285      *
1286      * On the first impression the method does to much. This is increased by
1287      * the fact, that is is called repeated times by the method determineId.
1288      * The reasons are manifold.
1289      *
1290      * 1.) The first part, the creation of sys_page, the type and alias
1291      * resolution don't need to be repeated. They could be separated to be
1292      * called only once.
1293      *
1294      * 2.) The user group setup could be done once on a higher level.
1295      *
1296      * 3.) The workflow of the resolution could be elaborated to be less
1297      * tangled. Maybe the check of the page id to be below the domain via the
1298      * root line doesn't need to be done each time, but for the final result
1299      * only.
1300      *
1301      * 4.) The root line does not need to be directly addressed by this class.
1302      * A root line is always related to one page. The rootline could be handled
1303      * indirectly by page objects. Page objects still don't exist.

1397      * the root line records are more liberal than that of the page record.)
1398      *

1400      * a short cut, it is replaced by the target page. If the page is a mount

1402      *

1406      *
1407      * (While upon the first accessibility check of the root line it was done
1408      * by loading page by page from the page repository, this time the method
1409      * checkRootlineForIncludeSection() is used to find the most distant
1410      * accessible page within the root line.)
1411      *
1412      * Having found the final page id, the page record and the root line are
1413      * loaded for last time by this method.

1415      * Exceptions may be thrown for DOKTYPE_SPACER and not loadable page records
