An example Java 11 project using Maven and JUnit 5 to demonstrate XML validation

Javadoc here:

Learn how to setup Java 13 in Travis
Learn how to create a module in Java >= 11 and how to have Maven running tests properly (right now, when module is defined, test will fail on running mvn verify due to lack of classes visibility)
Move to Java 13 and play with new String literals
Create an example for safe XML validation using Java (at least so that Sonar does not complain ... however, considering JAXP documentation)

My use case:
- run multiple validations against the same schema over and over
- It would be okay to keep the schema in memory, it is pretty large
- requires input (a) from file and (b) from string
- Instead of exceptions as result types, something more suitable shall be there as all processing shall happen within streams and completable futures
