title: Records spanning over multiple lines in graphviz
body: <p>I am trying to visualize a rather complex structure in the dot language.
  Because the record is big, I would like to write the code in mulitple lines. So instead of:</p>
  
  <pre><code>A11[label="A.11 Access Control|{A.11.1 Business requirements for access control|A.11.2 User access management}|{A.11.3 User responsibilities|A.11.4 Network access control}|{A.11.5 Operating System access control|A.11.6 Application &amp; information access control}|A.11.7 Mobile computing &amp; teleworking"];
  </code></pre>
  
  <p>I would like to enter it somewhat like this</p>
  
  <pre><code>A11[label="A.11 Access Control|
             {A.11.1 Business requirements for access control|A.11.2 User access management}|
             {A.11.3 User responsibilities|A.11.4 Network access control}|
             {A.11.5 Operating System access control|A.11.6 Application &amp; information access control}|
             A.11.7 Mobile computing &amp; teleworking"];
  </code></pre>
  
  <p>Unfortunately the parser for dot complains about a "string running past line end" or something alike. Does anyone know how to denote a linebreak in the code? I tried a <code>\</code> at the end of the line, but it didn't seem to work.</p>
  
  <p>thanks in advance</p>
