Update of /sources/public/html5/spec
In directory hutz:/tmp/cvs-serv1976

Modified Files:
	Overview.html 
Log Message:
Define 'URL' and 'valid URL'. Define 'script document context'. Introduce the term 'script browsing context' for the existing concept of 'browsing context associated with a script execution context' and use that term where appropriate. Define origin of onfoo='' scripts. Fix xref errors. Minor editorial fixes. (whatwg r1791)
