+=head1 BEHAVIOUR SWITCHES FOR SUB LAYOUTS
+
+Certain methods have been added to adjust behaviour in sub layouts. Most of these are single case uses.
+
+=over 4
+
+=item * sublayouts_by_name
+
+Contains a map that holds named sublayouts. If a sublayout needs to targeted
+directly, the compositing layout needs to add it here. Initially introduced for
+the ActionPlan.
+
+=item * webpages_path
+
+Overrides the default webpages path "templates/webpages". Used for mobile and design40 styles.
+
+Note that this does not have fallback behaviour by default. It is intended for
+stylesheets where the templates are so incompatible that a complete fork of the
+templates dir is sensible.
+
+=item * webpages_fallback_path
+
+Allows partial template sets to fallback to other paths in case a template
+wasn't found. Intended to be used in conjunction with L</webpages_path>.
+
+Note: in case a template can't be found at all, generic/error.html will be
+rendered, and the fallback doesn't work in this case.
+
+
+=item * allow_stylesheet_fallback
+
+Defaults to true. The default behaviour is that stylesheets not found in the
+stylesheet path of the user will fallback to files found in css/. This is
+usually desirable for shared stuff like common.css, which contains behaviour
+styling. If a stylesheet comes from a separate generator, this can be used to
+turn falllback off. Files can still be included with the complete path though.
+A request for "common.css" would not find "css/common.css", but a request for
+"css/common.css" would be found.
+
+Also see the next section L</GORY DETAILS ABOUT JAVASCRIPT AND STYLESHEET OVERLOADING>
+
+=item * html_dialect
+
+Default 'transitional'. Controls the html dialect that the header will
+generate. Used in combination with template overriding for html5.
+
+See also L<SL::Form/header>
