I remember discussing this with Johannes, and I think he had some reason that he was reluctant to check for the title attr there...? I hope he remembers because I can't seem to find record of it.
BTW, strictly speaking, we shouldn't be calling Html_parse_common_attrs() for every element because I believe there were a few that don't have %coreattrs under ATTLIST in the spec.
Of course you are right. I was too eager to send something in, and was really swimming over my head. Going back to Html_parse_common_attrs(), it is plain that this is for all elements having common attributes, whereas there are a handful of elements that do not allow for the title attribute, and are therefore excluded. I'll go back to learning how this thing works, and hopefully Johannes will have something to add about the conversation you mentioned in the meantime. Regards, Rob
