Documentation oversight

I see it is possible to have arguments like
-a
with no value, but how does the code know the input is -a with no value?

The resulting dictionary from a Parse will contain { "a": "" }; an empty string value. If using Populate the backing field will be set to true if a key matching the attribute is present.

Hope that answers the question.
