I would like to add my vote for this feature as well. The ability to export a Business Space as XML would be hugely useful.
For example, I need to rename an attribute. Unfortunately, the attribute name is referenced in various other objects, such as rules, queries, etc... Since AwareIM does not include any type of global search/replace capability, this means, I will have to manually rename all other references to the attribute, one at a time. What a nightmare!
If I could export the Business Space as XML, I could run a search/replace on the attribute name in a text editor and then re-import the Business Space.
This is one simple example, but I'm sure there could be numerous other examples where it would be faster and easier to edit the XML directly, rather than using the AwareIM Configuration Tool.
