Delivered Objects for Treasury Archiving

I see a handful of delivered objects for Archiving Treasury data. These include Archive Objects that start "TR_ARCH_...", like TR_ARCH_BANK_STMT or TR_ARCH_CSH_FCST_DTL. There are also related Archiving Templates like BANKSTMT or CASHFCST. However, I do not see anything in the PeopleBooks about Archiving Treasury data.  These objects also don't seem to represent full-picture archiving. For example, I don't see anything for archiving transactions (like cash transfers) or Deals. I was wondering if Archiving for Treasury is supported or if these Objects were created but aren't fully endorsed yet?
