11.2 Node libraries

Node rules specify the web page templates for a web. The template includes the title, header, and footer for each page. The WebMaker library includes several WML files for creating nodes. You include one node library file in your document to define the templates for web pages.

The node rules are used indirectly. Header rules reference the specific node rule they need if they produce new nodes. A first level header will use a level one node rule, an index heading will use an index node rule, and so on. Different pages require different navigation hyperlinks. These links appear in the headers and footers of a page and their appearance is defined in the node rules. Each node library includes several node rules because most web documents call for several kinds of web pages. Some also include specialized paragraph rules for indexes and tables of contents.

One of the node libraries must be included whenever you wish to use any node-generating rules from the headings library.
