My only objection to the <case value in "foo" "bar" "baz"> format is that it isn't consistent with the rest of the tags in the templating system - not that the templating system is 100% consistent in it's use of tag formatting. Something like <case value="foo bar baz"> or <case value_in="foo bar baz"> or even Ola's original proposal would be more consistent with the templating system's overall style where paramters use the parameter="some value" format.
