+Blurps (from cmsplugin-blurp module) can be used to define additional cell
+types, the CMS_PLUGIN_BLURP_RENDERERS variable is used to hold them, details
+can be found in the cmsplugin-blurp documentation.
+
+In addition to common attributes Combo supports a 'private' attribute, that can
+be used to exclude the given blurp from selectable cells.  The blurp itself can
+still be referenced manually in a template file. This is useful to avoid
+overwhelming the UI with blurps used in non-editable parts of the pages.
