===Contribute to Capella Project Explorer filters===

One can define contributions to Capella Project Explorer filter mechanism by creating a plugin which contributes to the following extension points:

*org.eclipse.ui.navigator.navigatorContent
*org.eclipse.ui.navigator.viewer

#The first extension point defines the new filters to be applied. It allows to define if the filter is applied by default and if it is visible in the filter view. 
<br>The filter is defined by referring to the Java class implementing the type of model element:
