Compiler Error C3134

'value' : value of attribute argument 'attribute' does not have valid type 'type'

A syntax error was detected when a value was assigned to an attribute.

For example, the following code will generate C3134:

#include <unknwn.h>
[module(name="xx")];

[object, helpstringdll(xx.dll), uuid("00000000-0000-0000-0000-000000000001")] // C3144
// try helpstringdll("xx.dll")
__interface IMyI {
   HRESULT xx();
};

void main(){
}
