Hi Akhilesh,
I agree with the way Harry suggested to look at the training records. They are "assets" for the organizations, they are documents that will be useful and support an organization, and its project managers.
On the other hand, EEFs are constraints for the project; e.g., HR management policies constraint the way a project manager plans and manages human resources.
Specifically to your point on the PMBOK discussion, the way I looked at that first item in Section 9.4.1.3 was: Human resources management policies about whatever it is listed after, including training records. In fact, when you work on team development, you need to take these policies into account, which—among other things—will discuss how to keep and maintain training records.
