invisible footnote (in note) in qandaset when using FOP to generate a .pdf

I do not know if the following issue is a docbook or a FOP issue.
But as a happy Docbook user, I start my search for a solution on this list.

The footnote content is lost (?) during the fo to pdf processing whenever I put a footnote in a qandaset.
Is this because of a wrong usage of docbook or a problem with my tool chain?

I use

- docbook-xsl-1.73.2

- saxon6-5-5

- fop-0.93

Note with a footnote¹

 

 

But the footnote content: "This is the 'invisible' footnote.&quot; is lost during the fo to pdf processing

 

Any hints about what I should do?

 

Thanks,
