OpenAPI property mismatch in Spec First approach IRIS documentation

Hello Community,

I just go through the IRIS latest documentation and I found the openAPI property is  "x-ISC_DispatchParent" was mentioned in sample swagger and its the actual property used in spec-first approach. However in some place the property was mentioned like "x-ISC_DispParent"  and bit discrepant
/confused. So, Just want to ensure Is this is an issue in documentation?

Thanks.

Ashok.
