Properties of risk version lists

The RIRiskVersionList entity has a number of properties. The properties related to the reinsurance plugins and web service are described in the following table.

Property	Description
`RiskNumber`	Unique identifier of a reinsurable risk.
`AllVersions`	Array of `RIRisk` instances that represent different versions of the same reinsurable risk.
`AttachmentInclusions`	PolicyCenter creates an `RIAttachmentInclusion` if the inclusion status of the attachment differs from the default, `Included`. Therefore, only attachments that are excluded or have special acceptance have an attachment inclusion row. When you exclude an attachment, PolicyCenter creates an `RIAttachmentInclusion` with the status set to `Excluded`.
`PolicyPeriod`	Policy period to which all versions of a reinsurable risk provide reinsurance coverage. Each version covers a different effective date range that does not overlap with the others. Only of one version is active at a time, though sometimes none are active.
