SQL has updates, but in SQL, the entire semantics of the data is
defined by the data model used for queries. In XML, most queries
produce results that no longer correspond to the schema defined by the
DTD or XML Schema, and many data sources may include additional
semantics that are not even known to the DTD or XML Schema. OQL (Object
Query Language) does not have an UPDATE or INSERT either, and for the
same reason.
