|This function writes a sequence, specified by <code>$items</code>, to a file specified by <code>$path</code>. If the specified file already exists, it will be overwritten.<br />The optional argument <code>$params</code> is used to set the serialization parameters, as defined in (see [[http://www.w3.org/TR/xslt-xquery-serialization/ XSLT 2.0 and XQuery 1.0 Serialization]] for more details).<br />If the <code>$append</code> flag is set to <code>true</code>, the serialized items are appended to the original file. If the file does not exist, a new one is created.<br />
