Configuration object for enabling the engine to process events represented as XML DOM document nodes.

Use this class to configure the engine for processing of XML DOM objects that represent events and contain all the data for event properties used by statements.

Minimally required is the root element name which allows the engine to map the document to the event type that has been named in an EPL or pattern statement.

Event properties that are results of XPath expressions can be made known to the engine via this class. For XPath expressions that must refer to namespace prefixes those prefixes and their namespace name must be supplied to the engine. A default namespace can be supplied as well.

By supplying a schema resource the engine can interrogate the schema, allowing the engine to verify event properties and return event properties in the type defined by the schema. When a schema resource is supplied, the optional root element namespace defines the namespace in case the root element name occurs in multiple namespaces.
