I have to admit i did not. When looking at it, it seems to me it 
introduces differences to the CSS 2.1 model regarding how for 
instance the underline is drawn.

"If an element contains no text (ignoring white space in elements 
that have 'all-space-treatment' set to 'collapse'), user agents MUST 
refrain from rendering text decorations on the element. "

This means no underline crossing the inline images if i read it 

Another interesting point:
"Names:  text-underline-mode, text-line-through-mode, text-overline-
Value: continuous | skip-white-space "
How is that to work if an ancestor of the text is in fact drawing the 
line? It sounds to me like every element having text decoration and 
have descendant text may need to know where every space in every 
descendant text is?

If the only real issue is the sub/superscripts then the choise to 
make the property:

Inherited: yes
Applies to: the text contents of all elements that have 'vertical-
align' other than 'sub' or 'super'.

seems like the obvious "minimal victory". This would cover the needs 
of authors and seems simple enough to implement. CSS3 can still apply 
all the new properties with the above restriction if i understand 

Even if the above is for some other reason not good enough, the 
models used in CSS 2.1 and CSS3 should be as similar as possible.
