Explanation Of 'ResultStatus' Flags

For the IdM Services, it is possible to have various returns for the 'ResultStatus' flags.  Here is additional explanation of these result flags:
 
NONE, SINGLE and MULTIPLE reflect the number of matches returned from a query
 
NA means we can’t determine any other result status because of either incorrect user input or there was some error or otherwise from the service. (e.g. there’s a maximum of 10 emails you can verify, if the user enters > 10 then the response will indicate that more than 10 were attempted but the resultStatus will be NA because ultimately no verifications were actually carried out).
 
(This is different from NONE which means a definite lookup was performed and no records were found.)
 
PICKLIST means the results offer a pick list to choose from in order to further refine a search – (currently only used in telephone service if a user has to choose from a list of possible localities because the original locality searched was too vague)
 
VERIFY is used in our validation products (e.g. telephone or email validation) it shows the response is a result of a validation rather than e.g. an address lookup.
