Build-time BPMN definition reader and runtime XML binding via JDK StAX.
The BPMN format module parses BPMN 2.0 XML definitions using JDK StAX — no Camunda, no Flowable, no vendor dependency. BPMN is treated as an authoring format, not a workflow engine. Definitions are parsed into BpmnIntermediateModel, then adapted into the canonical meta-model.
