Takeaways:

The easiest way to use JAXP as an XML Schema (XSD) processor to validate XML documents is to load the XSD document and create a javax.xml.validation.Validator instance to validate any XML sources.
Tutorial examples are provided to create a javax.xml.validation.Validator to validate XML documents parsed with DOM API and SAX API.
Tutorial examples are also provided to override the default validation error handler to continue validation when errors occur and print better error messages.
The default implemenation of JAXP API in JDK 13 does not support XSD 1.1 specification.
