How to get a reference to std:alloc etc

1  I'm puzzled as how to get a Doxygen comment with an std:: exception like
 
\throws std::alloc If memory is exhausted.
 
The exception  is provided by #include <exception>
 
but what, if anything, do I need to tell Doxygen to include?
 
(similarly for Boost exceptions, if I Doxygen-include /boost/exception/exception.hpp
 
I will get a load more things I really don't need?)
 
2  I'd also like to write
 
\throws Never.
 
but this provokes a warning because the syntax is 
\throws <exception-object> { exception description }
and "Never" is the description, not the name of an exception.
 
Any suggestions?
 
Thanks
 
Paul
