Detailed Description

template<typename T>
requires requires () { { T::classID() } -> std::convertible_to<CLID>; }
struct ClassID_traits< T >

This specialization is used for classes deriving from DataObject.

To avoid having a compile-time dependency on DataObject, we enable this based on whether or not T::classID() is defined.
