How to make FCKe not eat <% some attributes %>

Hi,

I am working on integrating FCKeditor into our Blogsystem wich offers custom Macros to insert images, downloadlinks, polls etc using <% poll id="112" %>, <% image name="bla" %> and so on.

Is it possible to make FCKeditor not "eat" (read: entitify) <% ... %>?
