[whatwg] meter and document conformance

Is a document non-conforming if it contains a meter element that does  
not have a value attribute and the algorithm http://whatwg.org/specs/ 
web-apps/current-work/#steps fails to return either number1 and  
denominator or number1 and number2?

I think such documents should be non-conforming.
