Hmmm, another thought. Does it make sense to include the following two things?
#1: versioning info. Often when I get a file, the version number is basically meaningless. Here's the versioning ranks I use:
0.10 Initial Conversion
0.20 Cover and Frontispiece
0.30 Sections, Chapters and TOC
0.40 Endnotes and/or Blockquotes
0.50 Initial Spellcheck
0.60 Mdashes and Hyphens and Ellipses
0.70 Italics, Bold, and Pre-Formatted Text
0.80 Reading Proof
0.90 Checked against Canonical Source
1.00 Touched Up and Packaged For Release
#2: structure hints. Should someone have to examine the entire source for a clue to how it's been assembled? Or could you add something like this as a comment?:
Title: h1 class="title"
Subtitle: h3 class="subtitle"
Chapter: h3 class="chapter"
Paragraph: p class="normal"
Epigram: p class="epigram"
