What am I doing wrong with my BitcoinXT test net setup?
Solution
This solution gains access to the coins that are unavailable via BitcoinXT.


Using the bitcoin client, export the private key using the command bitcoin-cli dumpprivkey "accountname".
Uninstall BitcoinXT and remove the existing block chain (usually stored in ~/.bitcoin ).
Install Bitcoin Core (not Bitcoin XT), start the bitcoin-d server.
While the new chain is syncing, import the old key with bitcoin-cli importprivkey "keyExportedInStep1"
Wait for blockchain to sync.


Discussion and Lessons Learned

I was not sure that the testnet work had separated, but the fact that the transaction I was looking for was not in the corresponding block number was a huge indication.  After uninstalling BitcoinXT and installing Bitcoin, I now see the "missing" funds referenced above.

What this means is that the test network has reached that point where BitcoinXT no longer recognizes transactions and block chains that are approved by standard Bitcoin Core clients.  While BitcoinXT is compatible still on a public network, the test network is no longer compatible.

This also means that there is a need for a BitcoinXT faucet. At the time of this writing, I have not found a faucet for BitcoinXT compatible transactions.

The screen shot below shows that I now have access to the coins that were previously lost.
