A great example, why "parent" attribute does not really work in TPMKey ASN.1 definition is Linux kernel.

We have explicit parameter for parent handle called 'keyhandle' because the attribute stored in the ASN.1 is useless and ambiguous data.

Also, 'rsaParent' is just weird thing to have. Why not just have the whole TPM2B_PUBLIC blob for the parent key and applications can cherry pick what they want instead? It makes zero sense.
