Saving a Double.POSITIVE_INFINITY writes Infinity instead of INF [message #635309]

Eclipse (3.5) Build id: 20100218-1602
EMF 2.5.0.v200906151043

I'm trying to save a org.eclipse.emf.ecore.resource.Resource containing a Double.POSITIVE_INFINITY as XML. But instead of writing "INF" EMF writes "Infinity".

Due to W3C Infinity is INF in XML.

Is this a BUG or is it possible to configure this?

Andreas,

We implement EDouble like this in EcoreFactoryImpl

/**
* 
* 
* @generated NOT
*/
public Double createEDoubleFromString(EDataType metaObject, String
initialValue)
{
return initialValue == null ? null : Double.valueOf(initialValue);
}

/**
* 
* 
* @generated NOT
*/
public String convertEDoubleToString(EDataType metaObject, Object
instanceValue)
{
return instanceValue == null ? null : instanceValue.toString();
}

And Double like this in XMLTypeFactoryImpl:

/**
* 
* 
* @generated NOT
*/
public double createDouble(String literal)
{
return literal == null ? 0.0 :
Double.parseDouble(collapseWhiteSpace(literal));
}

/**
* 
* 
* @generated NOT
*/
public String convertDouble(double instanceValue)
{
return Double.toString(instanceValue);
}

I've never given any thought to how infinity, NaN, and other special
things are handled...
