XML Validation against XSD 1.1 gives error with XERCES library

Question

I need to validate XML files against XSD 1.1 schema. My question is: Does the Xerces library supports now XSD 1.1?

    <dependency>
      <groupId>xerces</groupId>
      <artifactId>xercesImpl</artifactId>
    <version>2.12.2</version>
</dependency>

When i include this in my pom then it doesnot work . It gives following Error :

java.lang.IllegalArgumentException: No SchemaFactory that implements the schema language specified by: http://www.w3.org/XML/XMLSchema/v1.1 could be loaded

But when i add the following jars manually in classpath then it kinda works:

cupv10k-runtime.jar
org.eclipse.wst.xml.xpath2.processor_1.1.0.jar
xercesImpl.jar
xml-apis.jar

My Code :

   import javax.xml.validation.SchemaFactory;
    
   schemaFactory = SchemaFactory.newInstance("http://www.w3.org/XML/XMLSchema/v1.1");

Do we need to add the jars manually for this to work. Isn't the library avialable in maven? Plese help if anyone has any idea.

The blog article https://blog.adamretter.org.uk/xerces-xsd11-maven/ describes the dilemma and explains that the author set up https://search.maven.org/artifact/org.exist-db.thirdparty.xerces/xercesImpl/2.12.2/jar and that that way you can use e.g.

<dependency>
    <groupId>org.exist-db.thirdparty.xerces</groupId>
    <artifactId>xercesImpl</artifactId>
    <version>2.12.2</version>
    <classifier>xml-schema-1.1</classifier>
</dependency>

<!-- xpath2 and java-cup are needed at runtime
        for xercesImpl Schema 1.1 support -->
<dependency>
    <groupId>org.exist-db.thirdparty.org.eclipse.wst.xml</groupId>
    <artifactId>xpath2</artifactId>
    <version>1.2.0</version>
    <scope>runtime</scope>
</dependency>
<dependency>
    <groupId>edu.princeton.cup</groupId>
    <artifactId>java-cup</artifactId>
    <version>10k</version>
    <scope>runtime</scope>
</dependency>
