Your specs should belong to a single module. module1:myrec() isn't the same type as module2:myrec().
A bit off-topic but I wouldn't use a record over multiple modules (even though I've done it in the past, this is getting fixed). It's better to have your record belong to one module, make it opaque and to add functions to manipulate it without having to know what's in it. This way you can modify your record only in one place and not have to worry about breaking code everywhere.
