xml instance document

基本解釋

Both companies want the XML instance document to indicate the namespace from which each component derives its definition.
兩家公司都希望 XML 實例文檔指出每個組件從哪個名稱空間派生其定義。
Each XML instance document produced by IXRetail should specify a default namespace, which should be the IXRetail namespace.
IXRetail 産生的每個 XML 實例文檔應(yīng)指定一個缺省的名稱空間，它應(yīng)是 IXRetail 名稱空間。
This means that whenever the element BookSales is referenced, the XML instance document will include number and price information with the title, the author, and the ISBN (see Listing 7).
這意味著無論何時引用元素 BookSales ，XML 實例文檔都將在包含書名、作者和 ISBN 的同時包含銷量和售價信息（請蓡閲清單 7）。
