process.source.toc — Process a non-empty toc element if it occurs in a source document?
Specifies that the contents of a non-empty "hard-coded"
toc element in a source document are processed to
generate a TOC in output.
This parameter has no effect on automated generation of
TOCs. An automated TOC may still be generated along with the
"hard-coded" TOC. To suppress automated TOC generation, adjust the
value of the generate.toc paramameter.
The process.source.toc parameter also has
no effect if the toc element is empty; handling
for empty toc is controlled by the
process.empty.source.toc parameter.
