Changes

All functions share {{Mono|$db}} as argument, which may either be reference a string, denoting the name of a the addressed database, or a node from an existing node stored in a already opened database. The following errors may be raised by all functions:

* <b>[[XQuery Errors#BaseX Errors|BASX0001]]</b> is raised if the addressed index required by a function is not available.* <b>[[XQuery Errors#BaseX Errors|BASX0002]]</b> is raised if {{Mono|$db}} is references a node that is not stored in a database(i.e., but references a main-memory XML fragment instead).* <b>[[XQuery Errors#BaseX Errors|BASX0003]]</b> is raised if the addressed database {{Mono|$db}} cannot be opened.
