title: How to create a ClearCase branch to a specific directory
body: <p>I'm trying to create a ClearCase view that obtains all files with a certain label applied.  Additionally, I would like to be able to create a branch on files checked out in the "source" directory, and only the source directory (or its subdirectories). For example, I don't want to create a branch of files in the /vob/design directory.</p>
  
  <p>I have the following config spec, but no branches get created.  All checkouts occur only on the main branch.</p>
  
  <pre><code>element * CHECKEDOUT
  element * .../my_branch/LATEST
  element * /vob/source/MY_LABEL -mkbranch my_branch  # this should include subdirectories
  element * MY_LABEL 
  element * /main/LATEST
  </code></pre>
  
  <p>I have also tried the following, with the same unsuccessful results:</p>
  
  <pre><code>element * CHECKEDOUT
  element * .../my_branch/LATEST
  element * /vob/source/... -mkbranch my_branch 
  element * MY_LABEL 
  element * /main/LATEST
  </code></pre>
