[TYPO3-english] 'Content Type HTML' adds html heading tags when inserting an iframe

Hi all,

Why the 'Content Type HTML' adds those additional HTML heading tags when 
inserting an iframe calling a php script?

This happens using TYPO3 4.5 to 6.2.26. Have not tested vers. 7, 8 yet

I use Content Type HTML to insert iframes containing results from a php 
script.  The problem is that TYPO3 surrounds the iframe content with 
<HTML>, <HEAD> and <BODY> tags. Furthermore the additional <HTML> tag is 
closed twice as shown in the example bellow:

<!DOCTYPE html>
<html>
---
<head>
---
</head>
<body>
---
	<html>
	<head></head>
	<body>
	    My iframe HTML resultant code
	</body>
	</html>
	</html>
---
</body>
</html>

By the way, running the php script directly from the browser generates a 
clean HTML code.

Any idea how to get rid of those extra tags?

Thanks
