That would work fine because typo3.org is a truly external site.

The link is broken only if it links from one of my Typo3 websites to the 
other (both reside in the same page tree, but have different domain 
names). In that case, it doesn't matter if it is a link from RTE, a 
<link> tag, a <a> tag or just the plain URL.
