 /**
  * The ShardTransaction Actor represents a remote transaction
- *
+ *<p>
  * The ShardTransaction Actor delegates all actions to DOMDataReadWriteTransaction
- *
+ *</p>
+ *<p>
  * Even though the DOMStore and the DOMStoreTransactionChain implement multiple types of transactions
  * the ShardTransaction Actor only works with read-write transactions. This is just to keep the logic simple. At this
  * time there are no known advantages for creating a read-only or write-only transaction which may change over time
  * at which point we can optimize things in the distributed store as well.
