The method namespaceDeclarations takes no argument and returns an array
with the namespace declarations associated with the XML object it is
called on.

Here are some examples:

  var p = <xhtml:p xmlns:xhtml="http://www.w3.org/1999/xhtml"
xmlns:xlink="http://www.w3.org/1999/xlink">Kibology
for <xhtml:b>all</xhtml:b>.</xhtml:p>;

  alert(p.namespaceDeclarations().join('\r\n'));
  /* shows
  'http://www.w3.org/1999/xhtml
   http://www.w3.org/1999/xlink'
  */

  var xhtml = new Namespace('http://www.w3.org/1999/xhtml');

  // child element b with no own namespace declarations:
  var b = p.xhtml::b[0];

  // show differences between inScopeNamespaces and 
  // namespaceDeclarations:
  alert('Namespaces in scope:\r\n' + b.inScopeNamespaces().join('\r\n')
+ '\r\nnamespace declarations:\r\n' +
b.namespaceDeclarations().join('\r\n'));
  /* shows
  'Namespaces in scope:
   http://www.w3.org/1999/xhtml
   http://www.w3.org/1999/xlink

   namespace declarations:
   '
