I'm writing a book. The Part and Chapter pages are distinct from other pages,
and employ complex styles. I'm having trouble getting the TOC right.

The Chapter page is like this:

---------------
1 --- The Chapter Number (Style: "H2", auto-numbered)
Introduction --- The Chapter Title (Style: "My Chapter Title Style")
to This Topic

---------------

Part Number and Title are similar ("H1", "My Part Title Style").

I inserted TOC using H1/H2/H3. Obviously, only Part/Chapter Numbers showed
up in TOC; I need the Part/Chapter Titles there as well. How to do this? If
w/o programming, even better; if programming, how to do this?

Thanks a lot in advance!
