[css-counter-styles] counter(foo, undefined-style)

http://dev.w3.org/csswg/css-counter-styles/#extending-css2 extends the 
counter() and counters() function to accept a <counter-style-name>, but 
does not define what happens when no counter style is defined with a 
corresponding name.

Compare with http://dev.w3.org/csswg/css-lists/#propdef-list-style-type 
that defines list-style-type to fall back to 'none', and to CSS 2 where 
an invalid <'list-style-type'> drops the declaration.
