声明缺失 http://www.w3.org/XML/1998/namespace

Question

我有一个 xslt1.0 映射文件，顶部如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:s0="http://F.FlatFileSchema1" xmlns:xml="http://www.w3.org/XML/1998/namespace" exclude-result-prefixes="s0">
    <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
    <xsl:key name="groupbyproduct" match="Products" use="product"/>
    <xsl:template match="/s0:Product">
        <enfinity xsi:schemaLocation="http://www.intershop.com/xml/ns/enfinity/7.1/xcs/impex catalog.xsd http://www.intershop.com/xml/ns/enfinity/6.5/core/impex-dt dt.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.intershop.com/xml/ns/enfinity/7.1/xcs/impex" xmlns:xml="http://www.w3.org/XML/1998/namespace" xmlns:dt="http://www.intershop.com/xml/ns/enfinity/6.5/core/impex-dt" major="6" minor="1" family="enfinity" branch="enterprise" build="build">

当我在 Visual Studio 中使用 BizTalk 从 csv 创建 xml 文件时，顶部的声明如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<enfinity xsi:schemaLocation="http://www.intershop.com/xml/ns/enfinity/7.1/xcs/impex catalog.xsd http://www.intershop.com/xml/ns/enfinity/6.5/core/impex-dt dt.xsd" major="6" minor="1" family="enfinity" branch="enterprise" build="build" xmlns="http://www.intershop.com/xml/ns/enfinity/7.1/xcs/impex" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dt="http://www.intershop.com/xml/ns/enfinity/6.5/core/impex-dt">

我认为顺序并不重要，但在

xmlns:xml="http://www.w3.org/XML/1998/namespace"

请问如何确保包含此行？
