// Schema for DECL_ATTR:
//
// - Attribute name.
// - Class name without the 'Attr' suffix (ignored for
// - Options for the attribute, including:
// * the declarations the attribute can appear on
// * whether duplicates are allowed
// * whether the attribute is considered a decl modifier or not (no '@')
// - Unique attribute identifier used for serialization. This
// can never be changed.
//
// SIMPLE_DECL_ATTR is the same, but the class becomes
// SimpleDeclAttr<DAK_##NAME>.
