Fix error range for duplicate attribute

[xorye]

The error range for both AttributeNSNotUnique and AttributeNotUnique is now on the first occurrence of the duplicate attribute. If needed, it could be on the last occurrence of the attribute, but we would need a method like DOMNode.getAttributeNode(String prefix, String suffix), except it iterates through the list of attributes, backwards.

For the above screenshot, the arguments were:

arguments[0] = "xs:schema"
arguments[1] = "tns"
arguments[2] = "http://www.w3.org/2000/xmlns"
