what does <hashcode> mean in screen xml file

[damage]

i'm trying to script the generation of a bunch of screens and was wondering what does the <hashcode> field mean? can i just fill this in w/ some random number or is there some function to generate this hash?

hash code is a randomly generated UNIQUE number that cannot be the same for more than one button on the same screen I believe...perhaps the whole skin I cant remember. They are used for navigation overrides, so xlobby knows what button to go to. Its basically an internal xlobby mechanism for labeling buttons.
