Removes an attribute by local name and namespace URI. If a default
value for the removed attribute is defined in the DTD, a new
attribute immediately appears with the default value as well as the
corresponding namespace URI, local name, and prefix when applicable.
The implementation may handle default values from other schemas
similarly but applications should use
Document.normalizeDocument() to guarantee this
information is up-to-date.
If no attribute with this local name and namespace URI is found, this method has no effect.
Per [XML Namespaces] , applications must use the value
null as the
namespaceURI parameter for methods if they wish to have
|The namespace URI of the attribute to remove.|
|The local name of the attribute to remove.|
| NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NOT_SUPPORTED_ERR: May be raised if the implementation does not support the feature
