FCKEditor or the like for mixed content

Hello,

    Orbeon has a component called the "HTML Area" which is just a text area
with the FCKEditor wrapped around it.  Does anybody know if I can attach the
FCKEditor onto the xforms:textarea with the Firefox plugin?   Or can someone
point me in the right direction to make this happen?  I'd like to use the
textarea for mixed content editing.

Thanks,
Dustin
