User token associated with the document.
public string UserToken { get; set; }
The user token associated with the document. The default value is null.
User tokens can optionally be used with a document to restrict usage. Refer to Loading Using LEADTOOLS Document Library for more information.
This value is used if DocumentId is not null and it references a document in the cache that was stored with a user token. Eventually, the converter will call DocumentFactory.LoadFromCache to load the document. If a value is passed into UserToken, it will be set in the LoadFromCacheOptions.UserToken instance passed to that method.
