title: Disable specific dates on p:calendar
body: <p>Is it possible to disable specific dates (for example: 15th May or 23rd June) on the PrimeFaces 3.5 <code>&lt;p:calendar&gt;</code> component? There is min and max, but I need to disable specific dates like public holidays <strong>using el expressions so I can use dynamic dates.</strong></p>
  
  <p>Using Hieu's answer, make sure the dates you disable have NO leading zeros in front (eg. '03/03/2013' should be '3/3/2013').</p>
