#5 New ways to work with <extra> data

[Steven Thomas]

A DOM user has requested the ability to fill in the contents of an <extra><technique> by passing in a raw string of xml data. Maybe something like the following:

technique->setRawContents("<my_element><my_sub_element/></my_element>");

That should create two domAny objects and attach them to the technique.

Going in the other direction would also be nice.

char* rawContents = technique->getRawContents();
// rawContents to be freed by caller
