title: Create a Tag and Merge with a branch SVN
body: <p>On my production i have this latest branch "<code>PROD_BRANCH_URL</code>".
  For a change i  created a branch “<code>NEW_BRANCH_URL</code>” in which i do not have the changes of above branch. 
  Now the issue is new branch does not contain the changes of the latest branch that is in the Production.</p>
  
  <p>I want to create a tag from trunk and then merge changes from <code>NEW_BRANCH_URL</code> to the new tag. </p>
