h3. Usage of AMALTHEA Model Validation

The AMALTHEA model validation can be triggered by clicking on the "Validate" button of the Amalthea editor.

!../pictures/validation/profile_selection_dialog.png!

The dialog shows a list of profiles allowing the selection of specific validations.

The validation is either applied to all elements of the model (default: folder scope) or only to the elements of the current file.

If an error is found, it is shown in the Problems view of Eclipse. A simple double click on the error will lead you to the affected elements in the AMALTHEA model. The validation distinguishes between three error types: __errors__, __warnings__ and __info__.
