The i18n core working group still disagrees with your reply.
We have a scenario in mind with an XHTML document which contains an SVG  
image. If it is external, the language information does not apply anymore.  
Our concern is: what should happen if there is no "authoritative  
metadata"? We agree with the explanation you gave us, but would like to  
have a scenario for the case without "authoritative metadata", but with  
document internal data.

Regards, Felix.
