renaming a referenced table

[Rick Hillegas]

I am working on a patch (DERBY-6672) which lifts the following 
limitation in Derby: you can't RENAME a table referenced by a foreign 
key. The limitation seems to go back at least as far as Cloudscape 5.1 
but not as far back as Cloudscape 3.5 (which doesn't have a RENAME TABLE 
command). I don't have access to the code archaeology for this 
limitation. Could someone with access to the code archaeology help me 
understand the motivation for this limitation? I don't want to remove 
this limitation if it is going to cause some known edge-case to fail.

Thanks,
-Rick
