Calling clear() on org.eclipse.cdt.internal.core.settings.model.xml.XmlStorageElement does not remove all attributes from an element. 

Example: 
Calling clear on an element having 3 attributes(a, b, c)will only remove 2 attributes (a, c). The b attribute will not be cleared

The issue seems to be caused by following code in the clear() method and the way attributes are removed from the NamedNodeMap. 

NamedNodeMap map = fElement.getAttributes();
for(int i = 0; i < map.getLength(); i++){
	Node attr = map.item(i);
	if(isPropertyAlowed(attr.getNodeName()))
		map.removeNamedItem(attr.getNodeName());
}
