  -The `kie-maven-plugin` now performs by default pre-compilation validation of DMN model assets (ref: https://issues.redhat.com/browse/DROOLS-5020[DROOLS-5020]).
  +The `kie-maven-plugin` now performs default pre-compilation validation of DMN model assets. It includes the following enhancements:
   
  -Specifically:
  +- DMN model files are verified against the DMN specification XSD schema to ensure that the files are XML valid and compliant to the specification.
  +- The pre-compilation analysis is performed for the DMN model to ensure that the basic semantic is aligned with DMN specification.
   
  -- DMN model files will be checked against the DMN specification XSD schema, to check they are XML-valid and conformant to the specification (`VALIDATE_SCHEMA` flag)
  -- pre-compilation analsys will be performed on the DMN model, to ensure some basic semantic is respected accordingly to the DMN specification (`VALIDATE_MODEL` flag)
  +You can also override the default behavior by disabling the feature or performing a specific validation.
   
  -It is possible to override the default behavior, to disable completely or perform only a specific check, by supplying `kie-maven-plugin` configuration option `validateDMN`.
  -
  -The following example illustrates how to instruct the plugin to perform only the XSD schema validation:
  +For example, use the following configuration to perform only the XSD schema validation:
   ```
   <plugin>
       <groupId>org.kie</groupId>
  
positive.code: </plugin>
  ```
  
  The following example illustrates how to instruct the plugin to disable any pre-compilation validation of DMN model assets:
  ```
  <plugin>
      <groupId>org.kie</groupId>
  
negative.code:         <validateDMN>VALIDATE_SCHEMA,VALIDATE_MODEL</validateDMN> 
      </configuration>
  </plugin>
  ```
  
  NOTE: An unrecognized `validateDMN` configuration flag disables any pre-compilation validation and the maven plugin emits related log message.
