How to handle comma separated values in OLE DB Source query for a parameter variable from XML file in SSIS

Question

Hi,
I am using OLE DB Source to fetch the records with Data Access Mode as SQL COMMAND which is using the below query with a parameter,
SELECT CON.Title,CON.FirstName,EMP.MaritalStatus,EMP.Gender,EMP.Title AS Designation, EMP.HireDate, EMP.BirthDate,CON.EmailAddress, CON.Phone
from HumanResources.Employee EMP INNER JOIN Person.Contact CON ON EMP.ContactID=CON.ContactID WHERE EMP.Title in (?) 
In this query for the parameter I am passing the value from a variable and which is configured (XML Configuration). While passing value
Buyer it works correctly. But while passing values Accountant,Buyer
it is not working as expected.
How to handle while passing such multiple values Or is it possible to pass such values or not in SSIS 2012 ?
Kindly help me to find a solution.
NOTE: I placed the whole query in a variable as a expression as below it is working fine.
"select CON.Title,CON.FirstName,EMP.MaritalStatus,EMP.Gender,EMP.Title AS Designation,EMP.HireDate,EMP.BirthDate,CON.EmailAddress,CON.Phone from HumanResources.Employee EMP
INNER JOIN Person.Contact CON ON EMP.ContactID=CON.ContactID WHERE EMP.Title in ('" + REPLACE(@[User::temp],",","','")  +"')"
Any other solution is there ? without placing the query in a variable. May be a variable can have some limitations for no. of characters stored not sure just a thought.

Putting the whole thing into a variable is certainly a valid solution.  The other involves putting the comma delimited list into a table valued variable.
