TinyMCE vs W3C standards. Tables not working at all in tinyMCE.

Hi All

I am using Lenya 2.0.3 and tinyMCE editor to edit my pages. However 
tinyMCE editor is showing all the attributes that are depricated 
according to w3c recommendations for xhtml.
So whenever I try to save my page with having some deprecated attribute, 
all the changes which I have made to the page get lost.

Is there any way I can correct this? I tried integrating tinyMCE version 
3 but it did not worked with lenya 2.0 for me.

Tables is tinyMCE are not working at all. The error in the logs is:
