Additional changes:

- Standardized headings to ATX style (#, ##, ###).
- Converted indented code blocks and inline code with complex content to
triple-backtick fenced code blocks with language hints (xml, properties,
text).
- Fixed a broken/messy inline link within the Eclipse-SourceReferences
example.
- Removed unnecessary backslash escaping in XML comments.
- Updated the manual Table of Contents to match the generated anchor IDs
for the new headings.
