Re: Exceptions in Attribues(2), AttributesImpl

Hi, Karl --

The by-name getters are used for the purpose of testing for the 
presence of an attribute as much as getting its value, and something 
like this:

String s = atts.getValue("foo");
if (s != null) {
  doStuff(s);
}

is preferable to something like this:

if (isSet("foo")) {
   String s = atts.getValue("foo");
   doStuff(s);
}

If for nothing else, the former is more in the habit of Java 
programmers, but also it saves two traversals of the internal data 
structure.  (The same would be true for an implementation of Attributes 
backed by Collection APIs.)

My $0.02.
