Container provides optional special mechanism for Value storing. It's possible to configure external Value Storages via container configuration (available only via configuration). Value Storage works as fully independent pluggable storage. All required parameters storage obtains from its configuration. Some storages are possible for one container. Configuration describes such parameters as ValueStoragePluginimplementation class, set of implementation specific properties and filters. The filters declares criteria for Value matching to the storage. Only matched Property Values will be stored. So, in common case, the storage might contains only the part of the Workspace content. Value Storages are very useful for BLOB storing. E.g. storing on the File System instead of a database.

Container obtains Values Storages from ValueStoragePluginProvider component. Provider acts as a factory of Value channels (ValueIOChannel). Channel provides all CRUD operation for Value Storage respecting the transaction manner of work (how it can be possible due to implementation specifics of the storages).
