Beside the standard [http://www.w3.org/TR/xpath-functions-30/ XQuery Functions], BaseX offers additional function modules, which are listed in the following table.
All modules are statically bound, which means that they need not (but may) be explicitly declared in the query prolog.
With {{Version|7.3}} many new modules have been introduced, and existing functions have been updated and moved.
Next, many error codes have been updated and aligned with the specifications.
