raw2att accepts array, but sprintf doesn't

Browse Source 
it's not very likely to happen (it did in my case :-) ) but if the value is an array, sprintf will fail (because raw2att accepts array, but sprintf doesn't). i suggest to json encode any array data to ensure it's safely included in the html. Or we should throw proper exceptions to make sure invalid values do not result in a php error.
