The HTML output method would not be obsolete for HTML5 either. The  
XSLT proposal would either need to be updated to ignore the HTMLL5  
text/html serialization xmlns permitted attribute or would need to be  
made namespace aware for text/html serializations.

Without the HTML output method there would be no way to output text/ 
html serialized versions of HTML5 that didn't have errant end tags  
(like <br></br>).

This is strictly a namespace issue. The XSLT recommendation never  
anticipated namespaces or namespace declarations for text/html  
serialized elements. Another approach might be just to change the  
recommendation to strip xmlns declarations from the HTML output. It  
all depends on where the WG takes namespaces in that serialization.

Take care,
