  • SYS_WEB is an instance of PRIM_WEB
  • Refer to 11. Using SYS_WEB to access Browser and JavaScript Features

  • SYS_APPLN is an instance of PRIM_APPL
  • Refer to 11.9 Routing Path Parameters

  • The SYS_THEME is typically only used in the BEGIN_COM of a Web Page or Theme to nominate the base theme to be applied. Refer to 5.1 Themes for more information.
