Now that's even more subtle than putting the xmlns attribute (and thus
the namespace declaration) in the DTD!

Of course, you could combine the two subtleties by declaring a namespace
unused in markup or content by unobtrusively putting it in the DTD:

<!ATTLIST doc xmlns:aus NMTOKEN #FIXED "milu.do.some.magic" >

And then write an application acting accordingly ... magically ...

Whatever the merits of this approach, thanks for the useful additional
information.
