/**
* Collection of static methods so that XML assertion facilities are available
* in any class, not just test suites. Thanks to Andrew McCormick and others for
* suggesting this refactoring.
* Available assertion methods are:
*
* assertXMLEqual
* assert that two pieces of XML markup are similarassertXMLNotEqual
* assert that two pieces of XML markup are differentassertXMLIdentical
* assert that two pieces of XML markup are identical. In most cases
* this assertion is too strong and assertXMLEqual is sufficientassertXpathExists
* assert that an XPath expression matches at least one nodeassertXpathNotExists
* assert that an XPath expression does not match any nodesassertXpathsEqual
* assert that the nodes obtained by executing two Xpaths
* are similarassertXpathsNotEqual
* assert that the nodes obtained by executing two Xpaths
* are differentassertXpathValuesEqual
* assert that the flattened String obtained by executing two Xpaths
* are similarassertXpathValuesNotEqual
* assert that the flattened String obtained by executing two Xpaths
* are differentassertXpathEvaluatesTo
* assert that the flattened String obtained by executing an Xpath
* is a particular valueassertXMLValid
* assert that a piece of XML markup is valid with respect to a DTD: either
* by using the markup's own DTD or a different DTDassertNodeTestPasses
* assert that a piece of XML markup passes a {@link NodeTest NodeTest}
* All underlying similarity and difference testing is done using
* {@link Diff Diff} instances which can be instantiated and evaluated
* independently of this class.
* @see Diff#similar()
* @see Diff#identical()
