+### Including JAXB support 
+
+If you are using Java 11 or higher (including Java 17) and you wish to use [JAXB](https://docs.oracle.com/javase/tutorial/jaxb/intro/)
+with the Java Client, you'll need to include JAXB API and implementation dependencies as those are no 
+longer included in Java 11 and higher.
+
+For Maven, include the following in your pom.xml file:
+
+    <dependency>
+        <groupId>javax.xml.bind</groupId>
+        <artifactId>jaxb-api</artifactId>
+        <version>2.3.1</version>
+    </dependency>
+    <dependency>
+        <groupId>org.glassfish.jaxb</groupId>
+        <artifactId>jaxb-runtime</artifactId>
+        <version>2.3.2</version>
+    </dependency>
+    <dependency>
+        <groupId>org.glassfish.jaxb</groupId>
+        <artifactId>jaxb-core</artifactId>
+        <version>2.3.0.1</version>
+    </dependency>
+
+For Gradle, include the following in your build.gradle file (this can be included in the same `dependencies` block 
+as the one that includes the marklogic-client-api dependency):
+
+    dependencies {
+        implementation "javax.xml.bind:jaxb-api:2.3.1"
+        implementation "org.glassfish.jaxb:jaxb-runtime:2.3.2"
+        implementation "org.glassfish.jaxb:jaxb-core:2.3.0.1"
+    }
+
+You are free to use any implementation of JAXB that you wish, but you need to ensure that you're using a JAXB 
+implementation that corresponds to the `javax.xml.bind` interfaces. JAXB 3.0 and 4.0 interfaces are packaged under 
+`jakarta.xml.bind`, and the Java API does not yet depend on those interfaces. You are thus free to include an 
+implementation of JAXB 3.0 or 4.0 in your project for your own use; it will not affect the Java API.
