/**
* This package is Saxon's implementation of the JAXP API designed for executing XPath 1.0 expressions
* directly from a Java application. Saxon extends the interface to handle XPath 2.0, though if the application
* makes extensive use of XPath 2.0 features, then the s9api interface offers a better fit
* to the XPath 2.0 data model. The API can be used either in a free-standing
* Java application (that is, where there is no XSLT stylesheet), or it can be
* used from within Java extension functions called from XPath expressions within
* a stylesheet.
* The API itself is defined by JAXP 1.3, in interfaces such as javax.xml.xpath.XPath
.
* These interfaces are included in Java Standard Edition from JDK 1.5 onwards.
* The interfaces provided by Saxon extend the JAXP 1.3 interfaces in various ways. There
* are three reasons for this:
*
* Saxon supports XPath 2.0 rather than 1.0
* The package retains support for some interfaces that were provided before JAXP 1.3 was released.
* (Most of these extensions have been deprecated for several releases, and most removed in Saxon 9.6).
* There are methods that allow an escape into Saxon's more low-level APIs, needed by
* anyone doing serious software integration.
*
* For most applications the preferred interface is
* the s9api {@link net.sf.saxon.s9api.XPathCompiler}
