A nice article about using Custom Attributes in your own code

I was poking around the blogs posts on the Falafel site and I came across a nice concise example by John Waters of how to define and use custom attributes in your own code.  His example shows how to use custom attributes as a simple way to define tag values in sub classes without having to write the same code over and over again for each subclass.  It’s a short enough read that there’s no point in excerpting any of it here.
