Why can I set the feature on the `Validator` but not on the > `SchemaFactory`? The feature you're trying to set isn't relevant to the SchemaFactory, so it's not supported at that level of the API. The value of " http://xml.org/sax/features/validation"; is fixed to true on the validator. You cannot disable it. A Validator does validation. There's no reason to set that feature. > 2.

Generally the ones that apply are those which relate directly to the behaviour of schema validation. > FYI: the `SchemaFactory` I am getting is > `com.sun.org.apache.xerces.internal.jaxp.validation.XMLSchemaFactory` com.sun.org.apache.xerces.internal.* isn't Apache Xerces.
