[TYPO3-RTE] Custom tag and paragraphs

[Christian Lerrahn]

Hi,
I've written an extension that adds a common tag <fn> used for
footnotes in the editor. Generally that works fine with footnotes just
entered in the place where I want to refer to them and then being
rendered in the right place by the extension. However, I cannot get
this to work with footnotes that span several paragraphs. The RTE will
always believe that I'm ending the paragraph I am in as soon as I start
a new paragraph within the footnote. So, if I wanted to write something
like

foo bar bla bla<fn>test line
second parageraph in footnote</fn> bla bla bar foo

I'll get something like

<p>foo bar bla bla<fn>test line</fn></p>
<p>second parageraph in footnote bla bla bar foo</p>

However, this should look like 

<p>foo bar bla bla<fn><p>test line</p>
<p>second parageraph in footnote</p></fn> bla bla bar foo</p>

Is it possible to configure the RTE to behave like that? Or at least
ignore line breaks in the footnote?

Cheers,
Christian
