Re:fo:folio-prefix (and other) content

Thank you for your comment on XSL 1.1. The FO subgroup is proposing the 
following change that we hope will satisfactorily resolve your issue:

1) Add to the end of the last sentence

  The fo:folio-prefix formatting object does not directly produce any
  areas. Its children will be retrieved and used when formatting page
  numbers.

in the areas section of 6.6.13, 6.6.14 (fo:folio-prefix and -suffix)
the text:

", as described in 6.6.10 and 6.10.7."

2) Add to the end of the last sentence

  The fo:index-page-number-prefix formatting object does not directly
  produce any areas. Its children will be retrieved and used by
  fo:index-page-citation-list when formatting cited page items and
  cited page item ranges.

in the areas section of 6.10.2, 6.10.3, 6.10.8, and 6.10.9
fo:index-page-number-prefix, fo:index-page-number-suffix,
fo:index-page-citation-list-separator, and
fo:index-page-citation-range-separator
the text:

", as described in 6.10.7."
