IPublishTransactionsPublishTransactionId Property

When a message with a list is too large, the list may be published through a series of transactions. Each sub-message must have the same PublishTransactionId. It is the responsiblity of the publisher to ensure this and to break the original message up. The Receiver is responsible for re-assembling the messages. An empty string value is assumed to mean that the original message was small enought in size that it didn't need to be broken up.

string PublishTransactionId { get; set; }
