What does :: in an E4X XML statement do?

I have this XML and a statement of code is doing this call: 

var rootStory:XML = new XML(source);
var xml:XML = rootStory..*::TextFlow[0];

What does this line do, rootStory..*::TextFlow[0]?

UPDATE:
This was the comment that was with it: 

// Also note the use of "..*" below. We are using this to traverse the
// XML structure looking for particular tags and at the same time allow for
// any namespace. So, you might see something like <flow:TextContainer> or
// <TextContainer> and this code will capture both cases.

So it seems it is either looking for the string, "::" or is it that "::" is an operation like ".."?

:: follows the namespace portion of the query. Therefore, *:: is requesting results from any namespace.
