I'm currently looking into API documentation generation tools and I noticed that apparently there are no efforts going on in standardization.
Javadoc style is kind of an ubiquitous convention... it is used for Java (duh), PHP (PHPDocumentor, doxygen, Stubbles), C/C++ (doxygen again)... and there is even IDE support for it even in other languages that are not java.
Even NaturalDocs which has a completely different syntax for documentation has some compatibility for it.
So my question is: are there any efforts going on in standardizing in-code documentation syntax?, which can in turn be used for documentation generators or language metadata across different languages?.
