- The namespace code representing the (prefix, uri) pair of the namespace binding to be
added. If the target element already has a namespace binding with this (prefix, uri) pair, the call has
no effect. If the target element currently has a namespace binding with this prefix and a different URI, an
exception is raised.inherit

that do not already have a namespace binding for the specified prefix, recursively.
If false, the new namespace binding will not be inherited.

If this node is not an element, or if the supplied node is not an attribute, the method takes no action. If the element already has an attribute with this name, the method throws an exception.
This method does not perform any namespace fixup. It is the caller's responsibility to ensure that any namespace prefix used in the name of the attribute (or in its value if it has a namespace-sensitive type) is declared on this element.

If this node is not an element, or if the specified node is not an attribute of this element, this method takes no action.
The attribute object itself becomes unusable; any attempt to use this attribute object, or any other object representing the same node, is likely to result in an exception.

- the namespace prefix. May be the zero-length string, indicating
that there is no prefix. This indicates either the default namespace or the
null namespace, depending on the value of useDefault.useDefault
- true if the default namespace is to be used when the
prefix is "". If false, the method returns "" when the prefix is "".

- If this is non-null, and the result array fits in this buffer, then the result
may overwrite the contents of this array, to avoid the cost of allocating a new array on the heap.
