class_docstr: For the word (ie, node) of a dependency tree and its attributes. Inherits
  from the ``Element`` class of Python's ``xml.etree`` library.
  
  >>> desc_form = Form('described')
  >>> desc_form
  described_0
  >>> desc_form.set('Tense', 'Past')
  >>> desc_form
  described_0
  >>> desc_form / 'VBN'
  described_0/VBN
  >>> desc_form.full_str()
  'described_0 [Tense=Past,pos=VBN]'
docstr: Create a dependency between this form as governor, to
  the other as dependent. Adds the dependent to the children
  of this form. This is done by overloading ``operator.rshift()``
  (``a >> b``) to perform ``.append()`` upon ``Element`` of the xml
  library. Returns ``Dependency`` xxx
  
  >>> john = Form('John', 1) / 'NNP'
  >>> john
  John_1/NNP
  >>> loves = Form('loves', 2) / 'VRB'
  >>> loves
  loves_2/VRB
  >>> mary = Form('Mary', 3) / 'NNP'
  >>> mary
  Mary_3/NNP
