[daisy] RE: Auto TOC for a document?

[shivshan]

Hi
Thanks for your replies. This and section editing (in non-included docs) are
two areas where i wish i could contribute. However, i am totally new to
Cocoon and XSLT :(
1. Since we dont use included documents much, we can probably use the XSLT
approach. I assume this change should be made somewhere in layout.xsl,
correct? 
2. After a quick check, i found many javascript solutions for creating a TOC
from a doc. I quite like the way Dokuwiki and Dekiwiki do TOC. Will continue
to investigate.
Thanks
Shiva
