While Doc-To-Help Markup Language is the recommeded method of specifying conditional text, you can also use the classic, non-D2HML conditional text comments in your Word source documents.
The classic method is different from the D2HML method in the following ways:
• With classic, non-D2HML comments, only one condition can be applied to your conditional text. For example, if you want your text to appear in both JavaHelp and the Printed Manual but not in any other Help targets, there is no way of specifying both conditions. D2HML allows you to apply multiple conditions to the text. See Applying Multiple Conditions to Text for more information.
• The View Conditional Text feature can only be used to view conditional text that has been specified using the classic method. This feature has been retained to ensure compatibility with older Doc-To-Help projects.
• D2HML conditional text comments can be created manually, but Word conditional text comments can only be created using Doc-To-Help’s Condition window.
