+ contextPath with the leading '/' removed and any remaining '/'
+ characters in the path replaced with '#'.</li>
+ </ul>
+ When a version is specified, ##version is added to the contextName and base
+ name. To help clarify these rules, some examples are given in the following
+ table.</p>
+
+ <table class="detail-table">
+ <tr><th>Context Path</th><th>Context Version</th><th>Context
