I have never heard of a bot that truncates a HTML file at the download of 
the keyword tag. I think sending what is displayed first would actually be 
helpful to some bots. Anyway, I agree; Metadata tracking and searching are
very important. The lang attributes are used by speech synthesizers, 
modification dates are used to refresh pages etc. I don't propose a rewrite 
of the HTML DTD to a BODY, HEAD organization or a rewrite of any other HTML 
DTD. The entire language would need to be reviewed to allow each tag to 
stream. Frankly, I don't think it is that big of a problem. I think the HTML 
file can be streamed with the addition of tags that give a description of 
the HTML file. The colgroup and other individual descriptions meant to 
stream an individual tag would not be required. I don't think protocols for 
the organization of tags, in the head or body, would do as much harm as you 
imply.
