I attached two image and want to know if PrinceXML supports

- floating images across columns

- having multiple footnote sections directly under a part of a chapter or section

?

Sample document:

Using "float: prince-column-footnote" would probably get you the right output, but floating across two columns will not work at the moment unless you use a page float to float all the way across both, not half way across.
