That does not seem to be at variance with the Apple document previously  
referenced.  AFAIK the gcc Objective-C people regard the Apple  
documentation as definitive.

As I read the grammar, that should be a protocol declaration list thus:
@protocol <OutputStream, HDF5>;
and it should not be followed by
@end
because the first line ends in a semi-colon

Whereas that should be the start of a protocol declaration and have  
some more lines leading to:
@end

That command looks like it succeded.

That looks like the function 'generate-module-map' in some elisp  
program failing to parse the line
@protocol CreatedClass <Create, DefinedClass>
You would need to look at the lisp source for the function.

As I understand it, the elisp parser code scans the source code and  
produces a parse tree of classes, protocols etc. which is then used to  
produce jni stubs, documentation xml in DocBook format and other stuff.
