This package provides an alternative API for executing XPath expressions directly from a Java application: unlike the API in package `net.sf.saxon.xpath`, these interfaces are not dependent on JAXP 1.3. 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 preferred API for executing XPath expressions in Saxon is the `s9api` package. This package is older, and provides a lower-level interface that offers access to more internal details, but is not so convenient to use.
