 * The Free version of WPSSO JSON offers complete WebPage and BlogPosting markup,
   but only basic markup for other Schema types. The Pro version includes markup
   for all the other types. See [https://wordpress.org/plugins/wpsso-schema-json-ld/](https://wordpress.org/plugins/wpsso-schema-json-ld/)
   for more information on features etc.
 * The Event markup is a bit special in that it can include optional information
   on artists / performers / organizers (requires the WPSSO ORG extension) and location/
   venue (requires the WPSSO PLM extension).
 * The wordpress.org support forums are limited to Free plugin support. If you have
   any questions about Pro version features, you can submit a ticket at [http://support.surniaulula.com/support/home](http://support.surniaulula.com/support/home).
