The following is an excerpt from the website.
Disneyland, all of which belongs to the Disney Company, is located in Anaheim.
While I am aware of "all of which", "some of which", etc. usages, I think I've never heard of "all of that".
Disneyland, all of that belongs to the Disney Company, is located in Anaheim.
I believe the second sentence is grammatically wrong. A thought occured to me that it may be related to the nonrestrictive usage of relative pronoun. "That" cannot be used as nonrestrictive one.(after comma)
Can anyone please verify this?
