Warnings for old DOM specifications

Hi all,

A while ago I proposed adding warnings to a number of specifications to 
alert readers that those documents are no longer being maintained. [1]

As there seemed to be general agreement this would be good to do, I've 
written up some proposed wording; see the attachment.

Please let me know if you have any comments.

Thanks
Ms2ger
