title: What is the significance of REMOTEID attribute in Tally Voucher XML File?
body: <p>I'm working on a utility to import my statements in Tally as a voucher.
  What I wish to achieve is that if in future I send the same entry by mistake, Tally should be able to identify it as Duplicate and overwrite it instead of creating a new voucher entry. I found REMOTEID attribute in the XML file and looks like that can be used to identify unique ids but I couldn't find a comprehensive documentation of Tally's XML format for Import and Export.</p>
