1357 1396     DRB: I split out the subpieces into two procs because the subsite post instantiation proc
1358 1397     needs to be able to find the package's node in the site node map, which results in a
1359 1398     cart-before-the-horse scenario.  The code can't update the site node map until after the
1360 1399     package is created yet the original code called the post instantiation proc before the
1361 1400     site node code could update the table.
