Yes, you still see that wording because we are still arguing slightly 
about the *exact* way that XML literals will be described, and I do 
not want to rewrite the document more times that I absolutely must. 
Nevertheless, the decision to remove lang tags from XML typed 
literals has been taken and will be implemented, as I said in my 
message.

If you prefer, we will wait for your response until the relevant 
edits to the document have been completed. I will send you another 
message to trigger this issue, with the same subject line.
