XML Todo List

Hackers,

I'm interested in tackling some of the todo items in XML category. Being 
new to postgres hacking I'm hoping I chose an item that isn't more than 
I can chew in the first sitting. One item that has caught my eye that I 
(naively) hope isn't a huge todo is:

xpath_exists() is needed. It checks, whether or not the path specified 
exists in the XML value. (W/o this function we need to use weird 
"array_dims(xpath(...)) IS NOT NULL" syntax.)

Is any one else working on the XML todos who might have some friendly 
pointers to help me on my way or am I just better off getting some code 
together for general review?

Thanks,
