Transaction is one of the core types in Yrs. All operations that need to touch or
modify a document’s contents (a.k.a. block store), need to be executed in scope of a
transaction.
Iterator used to traverse over the complex nested tree structure of a XML node. XML node
iterator walks only over YXmlElement and YXmlText nodes. It does so in ordered manner (using
the order in which children are ordered within their parent nodes) and using depth-first
traverse.
