+ <!-- Used from template menu.funcs to sort a module's functions for the lefthand index list,
+ from the module's .xml file. Returns a value on which to sort the entity in question
+ (a <name> element).
+
+ Some functions are listed with the name as an attribute, as in string.xml:
+ <name name="join" arity="2"/>
+
+ Others use the element value for the name, as in gen_server.xml:
+ <name>start_link(Module, Args, Options) -> Result</name>
+
+ Additionally, callbacks may be included, as in gen_server.xml:
+ <name>Module:handle_call(Request, From, State) -> Result</name>
+
+ So first, get the name from either the attribute or the element value.
+ Then, reverse the case of the first character. This is because xsltproc, used for processing,
+ orders uppercase before lowercase (even when the 'case-order="lower-first"' option
+ is given). But we want the Module callback functions listed after a module's regular
+ functions, as they are now. This doesn't affect the actual value used in the output, but
+ just the value used as a sort key. To then ensure that uppercase is indeed sorted before
+ lower, as we now want it to be, the 'case-order="upper-first"' option is used.
+
+ This processing only affect the lefthand index list- the body of the doc page is not
+ affected.
