 > As the html is parsed into a DOM and then serialized back to a string,
 keeping the original white space/line breaks is impossible, except in a
 <pre>.

 As with most of everything related to software, not only is it
 '''possible''', it's also pretty easy to implement:

 @SergeyBiryukov: My plugin also prevents the issue you outlined above wrt
 html5 attributes.

 @scribu - Thanks again for resurrecting this issue and giving it serious
 consideration.  If you have any questions or need some help with the
 details in the future please feel free to email or tweet me.  I'm pretty
 proficient with both TinyMCE and dom parsing in general.
