[css3-lists] # in the grammar for additive-symbols

Hi,

In section 8.7 of the current editor’s draft for Lists 3, the grammar 
for values of additive-symbols reads:

     [ <integer> && [ <string> | <image> | <identifier> ] ]#

Shouldn’t the # be a + instead? If not, what does it mean? The current 
working draft has a +.

Regards,
