openoffice xlsm query
 

I want to attach a id to a cell value in openXML format. Is it possible to
do that? Something like:

<row r="1" spans="1:1"<c r="A1" t="s"<v id="myid"0</v</c</row

Just some way is it possible. It was possible to store ids in earlier
HTML/MHTML formats, but looks like in openxml its something which is really
difficult to do?
