It is a named argument (as separate to the default conventional of positional arguments):

it makes it easy for the reader to see that that value represents
it makes it easy for the writer to supply a value to the 17th optional parameter without needing to specify all the others (or include lots of commas, etc)

It's used to pass values for named parameters to a method, in this case the constructor of the RequireAuthorizationAttribute.
