disable-output-escaping: bad programming practice?

Hi,
I'm using cocoon-1.8.2 to produce DHTML out of xml rendered with xsl containing 
JavaScript.
In one of the js functions, I have to use the <xsl:text disable-output-
escaping="yes"/> containing <![CATATA[]]> sections to transmit the opening and 
closing <body> and <html> tags separately to the browser.
Unfortunately for me, cocoon puts an xsl-pi <?xslt-next-is-raw formatter-to-dom?
> before the HTML-code that should be sent directly to the browser, that the 
browser (naturally) cannot understand.
Using the disable-output-escaping is (according to the faq) supposed to be bad 
programming practice. Does anybody see in the case of using javascript an other 
solution? Hints or workarounds are very appreciated.

Thank you

Nathalie
