* 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/ws</nowiki></code> namespace, which is statically bound to the {{Code|ws}} prefix. Prior to {{Version|9.2}}, the module needed to be imported in the query prolog: <pre class="brush:xquery">import module namespace ws = "http://basex.org/modules/ws";...</pre> 
* As sessions are side-effecting operations, all functions are flagged as ''non-deterministic''. As a result, some query optimizations will be suppressed.
