+###### Duplicate xml sections detection
+
+Groovy closure (`pomXml`) could also be useful when you want to avoid duplicates.
+
+For example, static model would always apply specified sections:
+
+```groovy
+maven.pom {
+ developers {
+ developer {
+ id = 'test'
+ name = 'Test Test'
+ }
+ }
+}
+
+maven.pom {
+ developers {
+ developer {
+ id = 'test'
+ name = 'Test Test'
+ }
+ }
+}
+```
+
+This would produce duplicate in the resulted xml:
+
+
+```xml
+
+
+ test
+ Test Test
+
+
+ test
+ Test Test
+
+
+```
+
+Whereas groovy closure:
+
+```groovy
+maven.pomXml {
+ developers {
+ developer {
+ id 'test'
+ name 'Test Test'
+ }
+ }
+}
+
+maven.pomXml {
+ developers {
+ developer {
+ id 'test'
+ name 'Test Test'
+ }
+ }
+}
+```
+
+Would correctly detect duplication and the resulted xml would be:
+
+```xml
+
+
+ test
+ Test Test
+
+
+```
+
+It is a very rare requirement to avoid duplications (appeared when pom is configured from multiple places),
+but still could appear, and, in this case, groovy closue (`pomXml`) could be very useful.

###### Clashed tag names
As `pomXml` closure is normal groovy closure, you may face situations when tag name clash with some method in your gradle project.
