I think it's hard for us to know, in advance, how authors will use  
this. It could be that the author maintains a list of namespace  
declarations on an HTML root element in anticipation of using them on  
another XML root element later on. In processing, the author will add  
a corresponding namespace prefix to all of the HTML elements later  
(when it's turned into XML).

Who knows how this would be used? It just seems a little odd to tell  
authors this attribute is meaningless for text/html, but they better  
make sure it has the right value.

Take care,
