Note that WML supports CSS by writing the class
attribute with a reasonable default and several options for overriding the default. There are two reasons for overriding the default. The first reason is for people who already have a cascading style sheet with class names that do not map directly to the FrameMaker paragraph tags; those people can use the class
attribute to specify the class names they use in their style sheet. The second reason lies in the fact that FrameMaker tags are case-sensitive but CSS class names are case-insensitive. Thus, if people have a FrameMaker template with two paragraph tag names that differ only in case, they can use the class
attribute to distinguish between them by creating different names. See Section 12.4, "WML support for CSS".
