Common Desktop Environment: Help System Author's and Programmer's Guide
The HelpTag Document Type Definition (DTD) defines each HelpTag element and the syntax for its use. If you are not familiar with DTDs, refer to Chapter 8, "Reading the HelpTag Document Type Definition," for a description of the specification.
The HelpTag 1.3 DTD is also available in the Developer's Toolkit. It is located in the /usr/dt/dthelp/dthelptag/dtd directory and named helptag.dtd.
