[TYPO3] Wrap everything but header of a content element

[Vlatko Surlan]

I've found how to wrap just the header, and how to wrap the entire 
content element. But how do I wrap everything but the header.

I just tested it by modifying the tt_content.text.20.wrap. But when I 
change this and then add text/w image content elemtent then the image 
block is not included.

What I need is this:

<!-- content element -->
<h1>my header</h1>

<div class="myEverythingButTheHeaderWrappedWrap">
Here goes everything but the header regardless of the content element type.
</div>

Thank you.
