Added bodies to macros. Use the bodies of <dc:call-macro><body></dc:call-macro> as <dc:macro-body/> in tthe macro. Example: <dc:macro name="greet"><hello><dc:macro-body/></hello></dc:macro> <dc:call-macro name="greet"><planet>Earth</planet></dc:call-macro> Result: <hello><panet>Earth</planet></hello>
