A WikiLink that goes from one WikiPage to another one, on another site. Some of them are InterWikiLinks as defined in MeatballWiki.

----
Using "http:" (without quotes) will begin, and end, an ExternalWikiLink thusly: http://example.com/

Note: WikiLink''''''s are not the same as HTML links. <a href="http://example.com/">example</a> In fact, the HTML is ignored completely. See:
