This article is part of the [[XQuery|XQuery Portal]].It summarizes all error the codes of errors that may be thrown are raised by the BaseX standard features and functions of XQuery processor. As the original specifications are pretty comprehensive, we tried our best to make this overview comprehensible to a wider range of readers.
Original definitions of the error codes are found in the[http://www.w3.org/TR/xquery-30/ XQuery 3.0],[http://www.w3.org/TR/xpath-functions-30/ XQuery 3.0 Functions],[http://www.w3.org/TR/xquery-update-10/ XQuery 1.0 Update],[http://www.w3.org/TR/xpath-full-text-10/ XQuery 1.0 Full Text],and [http://www.expath.org/spec/http-client EXPath HTTP]Specifications.
