net.sf.saxon.query.XQueryExpression
XQueryExpression represents a compiled query. This object is immutable and thread-safe, the same compiled query may be executed many times in series or in parallel. The object can be created only by using the compileQuery method of the QueryProcessor class.

Various methods are provided for evaluating the query, with different options for delivery of the results.
