[TYPO3] html question

[Bing Du]

Hi,

Would anybody mind giving me a quick reminder?  I'm writing a document.  I
want to enter in the RTE the following text

<acronym title="loooong name here">ABCD</acronym>

And I want it to show up on the web page exactly like that without
converting &lt; to '<', etc.

How should I do that?

Thanks in advance for any help.
