while, when you check the spec for the possible values for
start-indent and end-indent, negatives _are_ allowed.
Indeed! I was only talking about overlapping areas causing an error, not
about the values for the properties. It is important to distinguish
properties from traits from areas generated by the objects and their traits.
Probably only useful
then, when the list-item-label itself is also outdented...
I highlight in my XSL-FO course the use of negative values for outdents in
table of contents processing: when entries for a table of contents span
multiple lines, you need the block's indents to reflect the wrapping points
on the line and an outdent on the first line to the start of the TOC entry
and an outdent on the last line to the end of the TOC entry. This is
depicted on page 150 of the Prentice Hall edition of our book and on page
156 of the fourth edition of the PDF rendition.
These outdents work just fine and reflect only a single line when there is
no wrapping of any text. Thus, negative values are very useful.
