/**
* Static utility for dumping info about common Xalan objects.
* Cheap-o string representations of some common properties
* of various objects; supports some formatting and encapsulation
* but could use improvements.
* Note: currently purposefully outputs plain strings, not
* any XML-like elements, so it's easier for other XML-like
* logging utilities to output our data without escaping, etc.
