nextToken

The nextToken value that's returned from a previous paginated DescribeRepositories request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. If there are no more results to return, this value is null. If you specify repositories with repositoryNames, you can't use this option.

This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.
