  This is a dead simple XML parser that uses libxml2 to parse an XML document
  into a dictionary. It is designed specifically for use with RestKit. It
  does not support any fanciness like Namespaces, DTDs, or other nonsense.
- It does not save attributes on tags, it only cares about nested content and text.
+ It handles text nodes, attributes, and nesting structures and builds key-value
+ coding compliant representations of the XML structure.
+ 
+ It currently does not support XML generation -- only parsing.
