Returns all child elements of the given name. Special handling for the following names is implemented:
- 'paramaters' returns all direct 'parameters' OR all 'parameters/parameter' child nodes
- 'formatters' returns all direct 'formatters' OR all 'formatters/formatter' child nodes

@param string $name name of child element

@return \DOMNodeList of all child elements with the given name in the default namespace
