Red Hat XML editor confused Maven pom.xml file with Ant build files

The Red Hat XML Editor seems to confuse Maven pom.xml files with Ant build files. The error icon is displayed in the gutter giving the following tool tip message:

Unexpected element "

{http://maven.apache.org/POM/4.0.0}

project"

{antlib:org.apache.tools.ant}

project

Due to this error, code completion does not work. The standard WTP XML editor is not affected of this problem and works as expected.
