new( first, second=nil, parent=nil ) public

Constructor. FIXME: The parser doesn’t catch illegal characters in attributes

first	Either: an Attribute, which this new attribute will become a clone of; or a String, which is the name of this attribute
second	If `first` is an Attribute, then this may be an Element, or nil. If nil, then the Element parent of this attribute is the parent of the `first` Attribute. If the first argument is a String, then this must also be a String, and is the content of the attribute. If this is the content, it must be fully normalized (contain no illegal characters).
parent	Ignored unless `first` is a String; otherwise, may be the Element parent of this attribute, or nil.

Attribute.new( attribute_to_clone )
Attribute.new( attribute_to_clone, parent_element )
Attribute.new( "attr", "attr_value" )
Attribute.new( "attr", "attr_value", parent_element )
