not really, attributes are part of C++0x specification using the syntax 
[[...]] but gcc had another syntax since a long time 
(__attribute__((...)) ):
http://gcc.gnu.org/onlinedocs/gcc/Attribute-Syntax.html
MSVC has something similar with __declspec

if you want other compiler to ignore your attribute, I think you need to 
put them in a macro:

#if METADATAPARSING
#define ADD_MYATTRIB(param) __attribute__((myattrib(param)))
#else
#define ADD_MYATTRIB(param)
#end

class A {
     int m ADD_MYATTRIB("blabla");
};


or something like that.

Your project seems interesting, will the code be public?
