[whatwg] Boolean attributes on datagrid

[Henri Sivonen]

"The multiple attribute, if present, must be either empty or have the  
literal value multiple. Similarly, the disabled attribute, if  
present, must be either empty or have the literal value disabled.  
(The actual values do not have any effect on how these attributes are  
processed, only the presence or absence of the attributes is  
important.)"

Allowing the empty string does not conform to the general policy on  
non-minimized boolean attributes.

I think it would be a good idea to state the conformance requirements  
and the processing model for boolean attributes once near the  
beginning of the spec. It would also be good to provide a way for  
identifying boolean attributes.
