| '''Errors'''
|{{Error|get|#Errors}} the value of an attribute could not be retrieved.
|-
|{{Code|get}}
|The stored attribute is no XQuery value.
→Conventions
* The module will be available if the {{Code|basex-api}} library is found in the classpath. This is the case if you use one of the complete distributions of BaseX (zip, exe, war).
* All functions and errors are assigned to the <code><nowiki>http://basex.org/modules/session</nowiki></code> namespace, which is statically bound to the {{Code|session}} prefix. Prior to {{Version|9.2}}, the module needed to be imported in the query prolog:<pre class="brush:xquery">import module namespace session = "http://basex.org/modules/session";...</pre>
* If any of the functions is called outside the servlet context, <code>[[XQuery Errors#BaseX Errors|basex:http]]</code> is raised.
* As sessions are side-effecting operations, all functions are flagged as ''non-deterministic''. As a result, some query optimizations will be suppressed.

| '''Summary'''
