MSIR.0846 NameAllowed not allowed after NameRequired
The NameAllowed keyword was specified on a parameter description of a method declaration, but an earlier parameter had been specified as NameRequired. This doesn't make sense, since any parameters after a NameRequired parameter cannot be specified positionally, so they are, effectively, NameRequired.
Move the NameAllowed parameter ahead of NameRequired ones, remove the NameAllowed from the parameter declaration, or change the NameAllowed to NameRequired.
