[www-html-editor] <none>

  Had a question about some coding.  I am using CS2 and was looking at CS 3 and noticed that while typing, inserting text, i no longer needed &nbsp for a space in the text.  Could you yell me if this is a change is xhtml or if it's cs3 related and also show me to some sort of documentation of this change?  
Thank you,
James
