## Uses of Package
org.apache.xpath.compiler

Packages that use org.apache.xpath.compiler
org.apache.xalan.templates: Implements the `Templates` interface, and defines a set of classes that represent an XSLT stylesheet.
org.apache.xpath: Implementation of XPath; for the most part, only classes meant for public use are found at this root level of the XPath packages.
org.apache.xpath.axes: Implementation of XPath LocationPath support -- primary classes are LocPathIterator and UnionPathIterator.
org.apache.xpath.compiler: Implements an XPath parser which produces an OpMap, and a so-called Compiler which produces an expression tree for fast evaluation.
org.apache.xpath.functions: Implements XPath functions -- each function is derived from Function, FunctionOneArg, Function2Args, etc, with number-of-arguments checking being applied mainly at compile time -- this package only implements XPath functions, XSLT functions are found in the "templates" package.
