Changes

This * The module will be available if the {{Code|basex-api}} library is included found in the classpath. This is the case if you use one of the complete distributions of BaseX (zip, exe, war) of BaseX. * All functions and errors are assigned to of the {{Code|<code><nowiki>http://basex.org/modules/sessions}} namespace, which must be dynamically imported. In this documentation, the namespace is bound to the {{Code|sessions}} prefix. Errors are assigned to the {{Code|http:</nowiki></basex.org/errors}} code> namespace, which is statically bound to the {{Code|bxerrsessions}} prefix. * If any of the module functions is called outside the servlet context, the error <code>[[XQuery Errors#BXSE0003BaseX Errors|BXSE0003basex:http]] </code> is raised. * If a specified session id is not found, <code>[[#BXSE0004Errors|BXSE0004not-found]] </code> is raised. * As sessions are side-effecting operations, all functions are flagged as ''non-deterministicnondeterministic''. This means that the functions As a result, some query optimizations will not be reordered by the compilersuppressed.
