One of the places I photograph allows commercial photography.

Their public photo policy says:
Commercial photography is allowed.
Images  of  exhibits,  animals,  and  outdoor  space  are  permitted  for
commercial purposes.  If  singular  images  taken are  to  be  used  for  commercial  purposes,  the
photographer must attribute the location on the image or in the caption. 

Given that this is their public statement, can I use this public photo policy they have as a property release and sell my photos under commercial license instead of editorial?
