It is documented but doxygen didn't like a macro that was inserted between the 
comment and the function. Should be fixed by r23070

I'd note that proj4 strings have not all the expressivity of WKT. In 
particular they cannot capture citation strings, or authority name and code. 
So the suitability of using them depends on what you want to do with them.
