// Assigns one or more tags (key-value pairs) to the specified Amazon Location
// Service resource. Tags can help you organize and categorize your resources. You
// can also use them to scope user permissions, by granting a user permission to
// access or change only resources with certain tag values. You can use the
// TagResource operation with an Amazon Location Service resource that already has
// tags. If you specify a new tag key for the resource, this tag is appended to the
// tags already associated with the resource. If you specify a tag key that's
// already associated with the resource, the new tag value that you specify
// replaces the previous value for that tag. You can associate up to 50 tags with a
// resource.
