The 'location' of the library. The exact value of this property depends upon the library implementation itself. However, generally if the Library exists on a server it may be the URL to that library, and/or if the library is stored on the file-system, it could be the directory path to the library. This is intended to be used in conjunction with the Library name to help identify a library.
