In Autodesk Architectural Desktop 2006 and earlier, the RoomObjects Property Set Definition held these properties; in Autodesk Architectural Desktop 2007, the SpaceObjects Property Set Definition does. Autodesk Architectural Desktop 2006 had a SpaceObjects Property Set Definition, but it was identical to the SpaceStyles Property Set Definition, and contained automatic properties associated with Spaces.

If you migrate previous drawings to 007, be certain to rename the RoomObjects Property Set Definition to SpaceObjects if you want to use the 2007 out-of-the-box tags. If you migrate both old drawings and old content, you would not have to make the change, but keep in mind that other Property Set Definitions with Location properties may also reference the room properties, so either bring all of your old sets and content or be prepared to edit property references if you mix and match.
If you have a custom tag that you want to use with the 2007 Property Sets, make a copy of the content file for use in 2007 [unless you will never use a previous version ever again], and then edit the view blocks, changing the attribute tag names to refer to the SpaceObjects Property Set Definition, rather than the RoomObjects Property Set Definition.
Also note that the "Name" property is no longer a manual property but now references a newly added automatic property source, which can be filled in on the Design tab of the Properties palette, in the General subheading of the Basic category. You can assign a List Definition that applies to Space Names if you like, to make it easier to enter names in a consistent manner. If you prefer multi-line tags that use multiple attributes for multiple lines, you will have to add the needed properties and create/migrate your custom tag.
