Model API Model Attribute
=========================

ModelAttribute is a child of ModelObject and can contain Metadata.

All mentioned functions are available on ModelAttribute which is made available in Freemarker/Velocity by iterating over the element tree in model.xml.
In any step of the operation process you can access ModelAttribute, which is always the currently active attribute.

For an image see :ref:`API_hierarchy`

|Eye M| Getter functions in Freemarker/Velocity can be accessed as an object property, so modelAttribute.getName() can be written as **modelAttribute.name**.
