An <code>XQueryExecutable</code> represents the compiled form of a query. To execute the query,
it must first be loaded to form an <code>XQueryEvaluator</code>.
</p>
<p>An <code>XQueryExecutable</code> is immutable, and therefore thread-safe. It is simplest to
load a new <code>XQueryEvaluator</code> each time the query is to be run. However, the
<code>XQueryEvaluator</code> is serially reusable within a single thread.
</p>
<p>An <code>XQueryExecutable</code> is created by using one of the <code>Compile</code>
methods on the <code>XQueryCompiler</code> class.
