It supports the exchange of large [[data sets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] in XML format, provides strict validation of conformance with the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] using a generic XML parser, and supports the transmission of partial [[data sets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] ([[incremental updates>>doc:sdmx:Glossary 2\.1.Incremental update.WebHome]]) as well as whole [[data sets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]].

320 320  Many XML tools and technologies have expectations about the functions performed by an XML schema, one of which is a very direct relationship between the XML constructs described in the XML schema and the tagged data in the XML instance. Strong data typing is also considered normal, supporting full validation of the tagged data. These message types are designed to support validation and other expected XML schema functions.
