title: UML - Representing third party libraries in class diagram
body: <p>Could somebody guide me on representing third party libraries in a class diagram.</p>
  
  <p>For instance I am trying to draw a class diagram for my logging functionality. Which internally uses 'log4net' for logging. And I want to represent 'log4net' in my class diagram as a third party library(may be another assembly).</p>
  
  <p>Thanks.</p>
