Using Doc-To-Help Markup Language Hot Spots in XML Comments

It is possible to use Doc-To-Help Markup Language (D2HML) in your XML source code comments (e.g., to create links from reference topics to narrative topics—written manually by the author).

To format a range of text in your XML comment with any D2HML style, use the <span> tag with a style attribute. Since it lets you use all styles, you have the full power of D2HML for creating hot spots of any kind. You can create topic links, keyword links, expanding text, and other kinds of hot spots. See Doc-To-Help Markup Language.
