	guid	The guid is a unique identifier that represents a point-in-time for the company listings. Each request will return a 'guid' attribute in the parent XML element. You may optionally pass this guid as a parameter to future requests. If no changes have been made, a lightweight XML response will include a 'current' attribute in the parent XML element which will be set to 'yes'.
