[Typo3] Solution for the p tag problems with complex HTML code in the RTE?

[Pieter]

  There were several threads recently about problems with the RTE:
- RTE replaces <div> with <p>
- Typo adds <p>&nbsp;</p> after h1 tags
- Getting rid of <p> altogether
- How to remove <P> Tags in table cells (build in RTE)
- RTE - remove <P> tag
 
This is all because the text from the RTE is stored in the database as 
human readable as possible.  For example, <p> and </p> tags from the RTE 
are stored as chr(10) (enter) in the database and replaced with <p> and 
</p> again when de content is shown on a web page.
 
This is fine if you have plain text in the RTE but htmlArea RTE can to a 
lot more.  People adding content to the website will use this extra 
functionality.  And problems like the ones listed above then start to 
occur. 
 
My idea to solve this:
 
Why not create a htmlArea version to edit the HTML content element?  
HtmlArea creates perfectly fine HTML code.  The text inside the HTML 
content element is stored to the database without any changes.  Isn't 
that a great marriage? 
 
I don't see any disadvantages for the moment, maybe some of you do?  
Don't have any idea how much effort it will take to implement this?
 
It would be great to have this functionality in tt_news too, but that 
might be a separate problem.
 
Kind regards,
Pieter
