XQuery includes:
- XQuery 3.1 Minimal Conformance: Provides Minimal Conformance (including try/catch and "group-by", as well as language features retained from earlier XQuery versions) as defined in section 5 of the XQuery 3.1 specification.
- XQuery 3.1 Modules: Provides the Module feature, which allows a query to be made up of multiple modules.
- XQuery 3.1 Serialization: Provides the Serialization feature. This allows the output of a query to be serialized as lexical XML, or in other formats including HTML, JSON, and plain text, under the control of serialization parameters contained either in the query itself, or supplied externally.

- Streaming with EE license: Provides saxon:stream(), an extension function to allow large documents to be processed without holding the whole document in memory.
