Do you want to give it a more descriptive name? You can do AppendASCII() instead
of Append(FPL())

[Evan Stade, 2014/01/31 04:09:52]

do you have a suggestion for the name? It holds "all data that libaddressinput
might want to save to disk".

[Lei Zhang, 2014/01/31 05:02:15]

"Libaddress Cache" ?

[Dan Beam, 2014/01/31 19:24:55]

there is no libaddress.

if you want to change it, "Address Validation" or "Address Validation Cache"
sound the best to me

[Dan Beam, 2014/02/01 00:43:21]

changed to "Address Validation Rules"
