Versioning

tosca_definitions_version is a top level property of the blueprint which is used to specify the DSL version used. For Cloudify, the versions that are currently defined are cloudify_dsl_1_0, cloudify_dsl_1_1, cloudify_dsl_1_2 and cloudify_dsl_1_3.

Example

The version declaration must be included in the main blueprint file.
