The version of LTI which will be used to access the published content.

LTI Advantage allows content to be published to pre-registered platforms without the need to make changes on the platform whenever new content is published. The security contract is between the platform and the tool.

Legacy versions (1.1 and 2.0), require that a new tool registration is created on the consumer for each piece of newly published content because each piece of published content has its own security contract with the consumer site and must be set up on a case by case basis.
