The mapping-schema attribute identifies the mapping schema to be used by the updategram.

Its expressions and their results are not necessarily XML data. It lets you evaluate XQuery expressions against XML data sources and process the results as XML data.

block provides only the Contact ID column; therefore, the updategram uses only the value to search for the record.
