Package com.saxonica.expr

This package contains classes used to support expressions and instructions that are new in XPath 3.0, XQuery 3.0, or XSLT 3.0, and that don't fit conveniently into a more specialized category (such as streaming). Most of these classes represent internally-generated expressions or functions on the expression tree; the package also includes the XPath 3.0 and XQuery 3.0 parser extensions, and the Saxon-EE optimizer.

None of these classes will be used by typical user applications.
