// A descriptor for defining project properties for a service. One service may
// have many consumer projects, and the service may want to behave differently
// depending on some properties on the project. For example, a project may be
// associated with a school, or a business, or a government agency, a business
// type property on the project may affect how a service responds to the client.
// This descriptor defines which properties are allowed to be set on a project.

// Example:
//
//    project_properties:
//      properties:
//      - name: NO_WATERMARK
//        type: BOOL
//        description: Allows usage of the API without watermarks.

// API services can define properties that can be assigned to consumer projects
// so that backends can perform response customization without having to make
// additional calls or maintain additional storage. For example, Maps API
// defines properties that controls map tile cache period, or whether to embed a
// watermark in a result.
//
// These values can be set via API producer console. Only API providers can
// define and set these properties.
