Spec json is invalid: missing field gasLimitBoundDivisor at line 23 column 4

[stone212]

Before filing a new issue, please provide the following information.

I'm running:

• Parity version: 1.7.8
• Operating system: Linux
• And installed: via binaries

I am creating a private chain spec file for a private network. I see that the chain spec file for mainnet has "gasLimitBoundDivisor" in the "params" section:
https://github.com/paritytech/parity/blob/master/ethcore/res/ethereum/foundation.json

So I attempt to duplicate that, and I also place mine in the same section. But when I do, I get this error:

Spec json is invalid: missing field gasLimitBoundDivisor at line 23 column 4

If I add the gasLimitBoundDivisor to the "engine" section (under its params) the error goes away. That matches the example on this page:
https://github.com/paritytech/parity/wiki/Pluggable-Consensus

But it does not match the official mainnet chain spec file linked to above.

    "gasLimitBoundDivisor":"0x0400"

add this on that line

Thank you but I already did that, as I said in my initial comment:

If I add the gasLimitBoundDivisor to the "engine" section (under its params) the error goes away.

But the issue that I opened regards the conflicting documentation.

Further, users upgrading from 1.7 should acknowledge the following changes:

-The chain-engine was further abstracted and chain-specs need to be upgraded. #6134 #6591

Move registrar, gasLimitBoundDivisor, and eip155Transition from engine (Ethash/AuthorityRound/etc.) to general params section.

Sorry, fat-fingered this issue too quickly, thanks for reporting, I updated the docs.
