[news.eclipse.tools.emf] EDate property. input format not Locale.ENGLISH

["Urs Frei" <urs.frei@xxxxxxxxxxxxx>]

Hello

I have an EDate member in my ecore model. In the property view I have to 
input a date in the format like this:

new SafeSimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'.'SSSZ"),
new SafeSimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'.'SSS"),
new SafeSimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss"),
new SafeSimpleDateFormat("yyyy-MM-dd'T'HH:mm"),
new SafeSimpleDateFormat("yyyy-MM-dd")

But I would like to have a German format. Is there a way to change the 
configuration? The definition for the format is in the class
org.eclipse.emf.ecore.impl.EFactoryImpl

And the SaveSimpleDateFormat is configured to
public SafeSimpleDateFormat(String pattern){
    super(pattern, Locale.ENGLISH);
}

The only way I found is to replace the element in the member EDATE_FORMATS. 
But I think it is not the perfect solution.

Have you any other ideas?

Thank you

Urs
