Error when converting XSD to Java using jaxb

Question

It has been some time since I used XSD, XML and JAXB. Now I'd like to use it again. Unfortunately I have a strange error that I cannot resolve.

Here is my build.gradle.

configurations {
    jaxb
}

dependencies {
    jaxb 'org.glassfish.jaxb:jaxb-xjc:2.3.6'
}

task genJaxb {
    ext.sourcesDir = "${buildDir}/generated-sources/jaxb"
    // that works! 
    // ext.schema = 'https://raw.githubusercontent.com/spring-guides/gs-producing-web-service/main/complete/src/main/resources/countries.xsd'

    // that DOES NOT work!
    ext.schema = 'https://cwe.mitre.org/data/xsd/cwe_schema_latest.xsd'

    outputs.dir sourcesDir

    doLast() {
        project.ant {
            taskdef(
                name: 'xjc',
                classname: 'com.sun.tools.xjc.XJCTask',
                classpath: configurations.jaxb.asPath
            )
            mkdir(dir: sourcesDir)

            xjc(destdir: sourcesDir, schema: schema)
        }
    }
}

My schema comes from Mitre https://cwe.mitre.org/data/xsd/cwe_schema_latest.xsd. The overall task should work as the result is fine for a different sample schema https://raw.githubusercontent.com/spring-guides/gs-producing-web-service/main/complete/src/main/resources/countries.xsd. Unfortunately I'm getting the following error when using the Mitre schema.

[ant:xjc] [ERROR] Property "Lang" is already defined. Use <jaxb:property> to resolve this conflict.
[ant:xjc] line 302 of http://www.w3.org/2002/08/xhtml/xhtml1-strict.xsd
[ant:xjc] [ant:xjc] [ERROR] The following location is relevant to the above error
[ant:xjc] line 303 of http://www.w3.org/2002/08/xhtml/xhtml1-strict.xsd

I did some research and I sounds like I have to use some custom binding. However I do not even find "Lang" in the XSD file.

Any ideas how I can generate the Java code? Thank you very much!
