Repository of sequence diagrams for design patterns <p>Is there a good repository of design pattern sequence diagrams? Most repositories of design patterns I know (<a href="http://en.wikipedia.org/wiki/Software_design_pattern" rel="nofollow">wikipedia</a>, <a href="http://sourcemaking.com/design_patterns" rel="nofollow">sourcemaking</a>) have only class diagrams, and many times this is not enough to understand what the pattern really does and how it should be implemented, and I think that adding sequence diagrams to the description of the pattern could fill the needed blank, but have not seen this done. So, have you seen such repository?</p>
