[oXygen-user] Which words does “Document: Count Words” count?

Hello all, Which words does “Document: Count Words” count? I would certainly hope it doesn't count the XML markup. Beyond that, we are using Track Changes with author mode, and we would like not to count deleted text that is still present (i.e., as a change to be reviewed). Does this menu item count that or not? Thanks in advance for your help, —Ruchira
