[Rt-devel] How to use the Attributes table?

[Kumar, Vasanth]

In the RT 3.2.2 release notes, it says:

    * RT now provides an 'Attributes' table, which allows local
developers
      to easily extend all of RT's database tables with new read/write
      attributes without needing to modify RT's core schema

But I can't seem to find any documentation on the Wiki site specifying
how to use this table.  Can someone please direct me to the appropriate
document?

Thanks.
