Have been playing with custom API modules and been a bit frustrated with the XML output mode...
Adding pseudo-element _attribs alongside _element for XML output. There doesn't seem to be a good way currently to specify both attributes *and* subelements -- '*' lets you have text and attributes, but not sub-elements and attributes. Contents of _attribs will be added as attributes without disturbing the sub-elements.
