I believe such a document is a very bad idea. All documents should be 
XML 1.0 if at all possible. This is far more interoperable than the 

The only case that's not possible is where someone wants to use 
post-2.0 Unicode characters in markup; e.g. by writing element names 
in Amharic. Assuming you don't need to do this, you should write a 
pure 1.0 document and ignore XML 1.1.

Note: I do not believe there is *ANY* need for allowing NEL in white 
space. Any document that uses this can easily be rewritten in an XML 
1.0 compliant way with carriage returns and linefeeds. Any competent 
developer with the slightest concern for interoperability or longterm 
storage will do this anyway, even if XML 1.1 allows NEL.
