We did, but I still contend that having the corresponding text (the 
"abcd") in the character data of the element is important, for example 
for ATs that inspect the DOM to find text, and for the DOM Selection 
object to be able to represent selections across the text.  (Yes, we 
have <tref> which also violates this...)

Section 14.9.4?  So yes something like that, but as I say I haven't yet 
come up with a syntax that I like.  Again I would prefer something that 
keeps the corresponding character data as text nodes in the document.
