286N/A/**
286N/A * Its better to extend the functionality of existing XMLAttributesImpl and also make it of type Iterator.
286N/A * We can directly give an object of type iterator from StartElement event. We should also have
286N/A * Attribute object of type javax.xml.stream.Attribute internally. It would avoid the need of creating
286N/A * new javax.xml.stream.Attribute object at the later stage.
286N/A *
286N/A * Should we change XMLAttributes interface to implement Iteraotr ? I think its better avoid touching XNI as
286N/A * much as possible. - NB.
