  The implementation of method org.w3c.dom.Document.createAttribute(String name) throws
StringIndexOutOfBoundsException when the argument is an empty string (See test.java below).

  Definition of the method in p. 1.2 "Fundamental Interfaces" of DOM Level 2 Core
(http://www.w3.org/TR/DOM-Level-2-Core/core.html#i-Document) doesn't forbid such cases:

  " createAttribute
              Creates an Attr of the given name. Note that the Attr instance can then be set on an
              Element using the setAttributeNode method. To create an attribute with a qualified name
              and namespace URI, use the createAttributeNS method.
              Parameters
                  name of type DOMString The name of the attribute.
              Return Value
                  Attr A new Attr object with the nodeName attribute set to name, and localName,
                        prefix, and namespaceURI set to null. The value of the attribute is the empty
                        string.

              Exceptions
                  DOMException INVALID_CHARACTER_ERR: Raised if the specified name contains an illegal
                  character. "
                  
  This bug is found in the build jaxp-1.1.1-b23-10_mar_2001 and affects an old TCK test
