FastHack 021-IdentityForApps challenge 02 - issue with restricting States to only 3 using StringCollection since the attribute is a built-in attribute

On 021-IdentityForApps challenge 02 there is an issue with the DataType and the form control to use on the data collection for the attribute State/Province.

On challenge 2 of this FastHack there is the request to restrict the list of States/Provinces to only 3 States; and it shows using a StringCollection to achieve a list during sign up.

The challenge reads: "It should be noted that CMC only is licensed to do business in the following states: New York (NY), Ohio (OH) and Pennsylvania (PA) (values between parentheses represent the values that should be stored in the directory)."

This particular attribute (State/Province) is a Built-In attribute of type String and you cannot modify its DataType to be a StringCollection.

Start with 021-IdentityForApps/Coach/02-susi.md and compare the State/Province instructions with the built-in attribute's String type. Clarify how the challenge should represent the three permitted states without treating State/Province as a StringCollection, then verify the revised instructions are consistent with the stated directory values.
