22 * A class to convert page titles on a foreign wiki (ForeignTitle objects) into
23 * page titles on the local wiki (Title objects), using a default namespace
26 * For built-in namespaces (0 <= ID < 100), we try to find a local namespace
27 * with the same namespace ID as the foreign page. If no such namespace exists,
28 * or the namespace ID is unknown or > 100, we look for a local namespace with
29 * a matching namespace name. If that can't be found, we dump the page in the
30 * main namespace as a last resort.
