I forgot to respond to this point. Again, this strikes me as another  
non-issue. When working with documents within just the HTML  
namespace, it's important to be consistent in those DOM calls. I  
don't know of any XHTML implementation that has a problem with  
creatElement() as long as you stick with non-NS methods throughout.  
Obviously , you cannot work with multiple namespace elements within  
one document. However, that should be the biggest caveat of all when  
vending as text/html: do not mix elements from different namespaces.
