Stax validating

St AX, on the other hand, is oriented towards state dependent processing.For a more detailed comparison, see When to Use SAX.

Note - In a nutshell, SAX is oriented towards state independent processing, where the handling of an element does not depend on the elements that came before.Setting up a program to use SAX requires a bit more work than setting up to use the Document Object Model (DOM).SAX is an event-driven model (you provide the callback methods, and the parser invokes them as it reads the XML data), and that makes it harder to visualize.If the schema definition does not define a target namespace, then it applies to the default (unnamed, or null) namespace.So, in our example, you would expect to see these target namespace declarations in the schemas: An array of Objects can be used only when the schema language has the ability to assemble a schema at runtime.
