# I'm sort of new to this XML stuff and maybe I haven't grokked the basics , but here's what I am trying to do 
# I need about 10 different request to a server and they share common code. I want to keep things DRY 
# and use a sort of template system where the "header stuff stays the same and I use partials to inject into
# the XML tree
