If an author uses unnamed styles in the body of their html, the difficult 
part is not overriding the author's style, but knowing what to use in 
place of it.  The reader's UA can only override it by replacing it with 
the default, so that the reader won't have any idea that the author 
wanted a special style for that piece of text.  If someone uses a style 
often, and a reader wants to change the way that it is presented to him 
without forcing it into the default presentation, he has no way to do 
so.  On the other hand, if the author names the style then the reader can 
add that stylename to his own stylesheet (with weight "important" so that 
it overrides the author's choice).
