Or better, for forward compatibility (we may want to include more
things apart from nHeight and hashWitnessesRoot in the future):

struct hashRootStruct
{
 uint256 hashMerkleRoot;
 uint256 hashWitnessesRoot;
 uint256 hashextendedHeader;
}

For example, we may want to chose to add an extra nonce there.
