19.2.1 Understanding trails of links
A trail of links, often called a "breadcrumb trail", typically looks something like this:
Home & Garden > Kitchen > Small appliances > Coffee makers
The trail does not necessarily consist of links someone followed to reach a given page; instead, it represents the hierarchical position of the page in the structure of the HTML document.
Each heading in your FrameMaker document that has subheadings can be used as a link in a trail leading to successively lower subheadings. For each trail of links Mif2Go inserts the current value of predefined macro <$_trail>, which consists of the following:
• Starting HTML code for the trail
• Text of each item in the trail (content of the heading in question)
• Separator code between items in the trail
