## create-attribute

Creates a special "attribute descriptor" object.
attribute create-attribute ( attrname string, attrvalue string);
Description

This is an internal XQUERY function and you will probably never need to call it explicitely. It is not a part of library of standard XQUERY 1.0 functions.

This function creates an special object, called "attribute descriptor", which may be used only as argument of create-element() XQUERY function. Every attribute descriptor will force create-element() function to add an attribute with specified name and value into opening tag of the created element. If attribute with such name already exists, its value will be replaced.

Parameters
attrname – Name of attribute which should be created or changed
attrvalue – Value of of attribute
Return Types

Attribute descriptor
