 By creating mapping rule you can specify how KX 13 NodeAliasPath (stored in content item) should be mapped into XbyK page path.
 Rules are ordered. The first rule that matches NodeAliasPath will be used. You can use variable tokens when creating mapping rules - see below.

 It is up to the user's responsibility not to create rules that map different content items NodeAliasPath to a single product page tree path.
-Such a case leads to an overwrite of the linked content item for a particular page.
