I am not sure which part duplicates the text that you quoted? The original text only mentions the supplied values. The proposed changes add that there may be additional parameters. Are you saying that these additional parameters are "implied" by the part that you quoted?

'It' refers to the parameters containing all of the parameter values including the supplied ones and provider-generated ones if any.
