docbook.css.link boolean docbook.css.link Insert a link referencing the default CSS stylesheet Description The stylesheets are capable of generating a default CSS stylesheet file. The parameters make.clean.html and docbook.css.source control that feature. Normally if a default CSS file is generated, then the stylesheet inserts a link tag in the HTML HEAD element to reference it. However, you can omit that link reference if you set the docbook.css.link to zero (1 is the default). This parameter is useful when you want to import the default CSS into a custom CSS file generated using the custom.css.source parameter.
