Unwanted attributes not removed

[alexjfisher]

Consider this XML file

<settings>                                                                                                                                                                                                                                   
  <setting name="foo" unwanted_attribute="bar">baz</setting>
</settings>

and this puppet code

xml_fragment { 'test':
  path    => 'test.xml',
  xpath   => '/settings/setting[@name=\'foo\']',
  content => {
    value      => 'baz',
    attributes => {
      'name' => 'foo',
    },
  },
}

I would expect the puppet to remove unwanted_attribute, but this doesn't happen.

I think there is a route to doing this by using purge on the settings tag, which would remove any tag that isn't managed. Having the module remove unmanaged tags specifically would probably need to be managed via an optional parameter to the module.
