CTXSYS and PORTAL30 invalids after upgrade

Benette asked me about CTXSYS and PORTAL30 invalids which had resulted after upgrade. I asked him for a list and this is what he gave me:

APPS Package Body AST_OFL_TERR_MISS_ASGN_REPORT
APPS Package Body FND_OID_DIAG
CTXSYS Procedure WWSBR_CORNER_CTX_202
CTXSYS Procedure WWSBR_DOC_CTX_202
CTXSYS Procedure WWSBR_PERSP_CTX_202
CTXSYS Procedure WWSBR_THING_CTX_202
CTXSYS Procedure WWSBR_TOPIC_CTX_202
PORTAL30 Package WWV_MONITOR_WEBVIEW
PORTAL30 Package WWV_QBE_TABLE
PORTAL30 Package WWV_RENDER_QBE
PORTAL30 Package WWV_SYS_RENDER_QBE
PORTAL30 Package Body DBE_TABLE_ACTION

The simple answer to all the invalids above is: "Drop them, they are not needed." The Metalink Notes which advise this are:

444348.1 for Portal30 invalids
458370.1 for CTXSYS invalids which are calling the PORTAL30 invalids
352808.1 advises dropping AST_OFL_TERR_MISS_ASGN_REPORT as it is no longer used.
380480.1, 386746.1 and 444348.1 advise dropping DEBUG_CARTX
360285.1 advises dropping FND_OID_DIAG if you are not using OID/SSO.
