The sole requirements it that a dash appears *somewhere* in the name, so it can occur between or around significant or insignificant parts, and there's no way to tell automatically what parts are insignificant. 121750 2 hayato 2015-07-06 08:17:02 +0000 Moved to https://github.com/w3c/webcomponents/issues/201
