Dave,

The is a special note in XSL 1.1 spec for this case:
"An fo:folio-suffix is not permitted to have an fo:page-number, 
fo:page-number-citation, or fo:page-number-citation-last as a descendant."
http://www.w3.org/TR/xsl/#fo_folio-suffix

Obviously, if that note was not there in the Spec, it would allow loops: 
the inner page number would need to be surrounded by some folio-*, 
bringing in yet more page numbers and so on.

The same note applies for fo:folio-prefix.

The fact that you could fool the validator by wrapping 
fo:page-number-citation-last in an fo:inline inside an fo:folio-suffix 
-- that is a bug. However, we won't fix it at the place where it is, 
because the whole stylesheet that performs folio-* resolution we be 
re-factored into Java code for performance.

Anyway, I'll pay attention to these possible loops and their detection. 
Thanks for reporting!
