1.2 Changes between r2.1 and r3.0

There are a large number of small changes throughout the data dictionary – these are not listed at a detailed level, however if this is required please contact technicalcomments@allianceforparkingdatastandards.org. Structurally, the following changes have been introduced:  New tables have been introduced for each package in the first section of the data dictionary, indicating details of specializations where these are appropriate.  References to entities (classes, attributes, etc) now include reference to the parent package.  Definitions have been provided for all associations - many were previously empty.  Where attributes are typed as References, the target class of the Reference is provided.
