This can be explictly stated using Content-Script-Type HTTP header/meta  
and Mozilla's MIME type parameter:
<meta http-equiv="Content-Script-Type" content="text/javascript; e4x=1" />

http://developer.mozilla.org/en/docs/New_in_JavaScript_1.6
http://www.w3.org/TR/html401/interact/scripts.html#h-18.2.2.1

However since the e4x type parameter seems to be only affecting parsing of  
comments and CDATA inside <script>, it's irrelevant for attributes, so I  
think it shouldn't be required and E4X should work in  
attributes/bookmarklets by default.
