Newer plugin version (5.1.0, 5.0.0, 4.4.2) is not honoring embedded bindings.

[SantoshKumar4]

We are upgrading the gradle version so we needed to upgrade the plugin also. Unfortunately the newer plugin version is NOT honoring embeded bindings present in the xsd file. Tried all the newer version but got the same result.
Previously we were on 2.0 plugin version and it honored the embedded bindings. Please suggest what changes I need to make.
Tried it on Java 8 and Java 11, I see the same behavior in both setup.
I used xjc commandline (Java 8) and it honored the embedded binding and didn't create ApiValidator class. (details below)

classpath group: 'com.intershop.gradle.jaxb', name: 'jaxb-gradle-plugin', version: '5.1.0'

build.gradle:

jaxb {
    javaGen {
        name {
            schema = file('src/main/resources/xsd/Validation.xsd')
            packageName = 'a.b.c.d.e.f.g.model'

        }
    }
}

And xsd file is below and embeded binding is ApiValidator. This class is already present and I want to use that.

Downloaded 3.0.0 version from https://eclipse-ee4j.github.io/jaxb-ri/ and ran the xjc.sh and I see the same behavior (ApiValidator.java) is getting created.. so the behavior is consistent. Doesn't seem to be the issue with newer plugin version.
Still not sure, how to let it use embedded bindings?
I will go ahead and cancel this as issue doesn't seem to be plugin related.

Using the xjc.sh command line, found out that the issue was with the jaxb version.
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" jaxb:version="2.0"
The issue went away once I updated the version value to 3.0.0.
