Advantages of TinyXML-1
1. Can report the location of parsing errors.
2. Support for some C++ STL conventions: streams and strings
3. Very mature and well debugged code base.

Note that (currently) there is a performance impact for using COLLAPSE_WHITESPACE.
It essentially causes the XML to be parsed twice.
#### Error Reporting
TinyXML-2 reports the line number of any errors in an XML document that
cannot be parsed correctly. In addition, all nodes (elements, declarations,
text, comments etc.) and attributes have a line number recorded as they are parsed.
This allows an application that performs additional validation of the parsed
XML document (e.g. application-implemented DTD validation) to report
line number information in it's errors.
### Entities
TinyXML-2 recognizes the pre-defined "character entities", meaning special
