I've opened an issue in the issue tracker, but I'm reluctant to add a 
comma right away. The comma in CSS often, though not always, signals an 
alternative, e.g., in 'font-family', where the commas separate fallback 
fonts, used only if the fonts before it aren't usable.

We are also discussing a so-called "functional notation" for the 
template (to make it easier to add alternative notations for templates 
later, in case we discover the need for that). In such a notation, a 
comma would fit more naturally, e.g.:

    display: template("a b c",
                      "a d c");


PS. Tracker, this is CSS-ISSUE-199.
