But to get ahead for you. *|* represents the "all elements in namespace" selector. According to W3C, the selector is divided into:

ns|E

Where ns is the namespace and E is the element. By default, namespaces are not declared. Then, unless the namespace is explicitly declared, *|* and * will select the same elements.
