Hi Hongjun,

StringRef-ization and ArrayRef-ization are ongoing cleanup tasks, they are
not particularly tied to anyone and probably a good way to get your feet
wet.

I believe that the XML representations of ASTs nodes would require a higher
degree of expertise on the Standard because of the translation phase (ie
not tying the representation in XML to the classes used).
