xml backend does not follow 'the spec' #62
Description
XML backend does not follow 'the spec', http://www.xml.com/pub/a/2006/05/31/converting-between-xml-and-json.html such as xmltodict (https://github.com/martinblech/xmltodict) looks so.
In [1]: import anyconfig.backend.xml as X, xml.etree.cElementTree as ET
In [2]: X.elem_to_container(ET.XML("<e/>"), dict, {})
Out[2]: {'e': {}}
In [3]: X.elem_to_container(ET.XML("<e>text</e>"), dict, {})
Out[3]: {'e': 'text'}
In [4]: X.elem_to_container(ET.XML("<e name='value'/>"), dict, {})
Out[4]: {'e': {'@attrs': {'name': 'value'}}}
In [5]: X.elem_to_container(ET.XML('<e name="value">text</e>'), dict, {})
Out[5]: {'e': {'@attrs': {'name': 'value'}, '@text': 'text'}}
In [6]: X.elem_to_container(ET.XML('<e><a>text</a><b>text</b></e>'), dict, {})
Out[6]: {'e': {'@children': [{'a': 'text'}, {'b': 'text'}]}}
In [7]: X.elem_to_container(ET.XML('<e><a>text</a><a>text</a></e>'), dict, {})
Out[7]: {'e': {'@children': [{'a': 'text'}, {'a': 'text'}]}}
In [8]: X.elem_to_container(ET.XML('<e> text <a>text</a></e>'), dict, {})
Out[8]: {'e': {'a': 'text'}}
