## AI overview

OpenAPI 3.2 expands XML modelling with clearer support for namespaces, attributes, mixed content, and precisely named nested wrappers. The article explains how these capabilities address limitations in OpenAPI 3.1 and reduce reliance on parallel XSDs, proprietary extensions, and prose documentation.

## Source excerpt

OpenAPI 3.2 modernises XML support with richer modelling, proper attribute handling, and nested structures. It removes old workarounds and gives enterprise teams clearer, more accurate ways to define their XML based APIs.
