Chapter-Number as initial (drop cap?) for bible (xsl-fo and xml to pdf)

I need help again. I'm almost done with my idea and actually just need some fine tuning of my bible. Is it possible that the chapter number stand as drop cap? Here is an example from another bible: https://i.sstatic.net/1uRTp.png

Thank you very much!

Just use floats, they should work with FOP. The structure you are looking to create should be something like this:

<fo:block>
  <fo:float float="start">
   <fo:block margin="0pt" color="red" text-depth="0pt" font-size="62pt" line-height="40pt" font-weight="bold" font-family="Courier">F</fo:block>
  </fo:float>loats dimensions derived from its content width/height, accompanying text should wrap around floating block. Drop capital in this paragraph implemented using side float that contains fo:block with single big letter "F". Floats dimensions derived from its content width/height, accompanying text should wrap around floating block. Drop capital in this paragraph implemented using side float that contains fo:block with single big letter "F".
</fo:block>

See http://www.renderx.com/usecasestest.html "creating drop capitals using side floats"

Used this test file and FOP 2.5, the result is:

There is no need for any extensions to any FO formatter to accomplish this, as long as they support floats.
