更新XMLschema(向上兼容性)。
如果需要将两种不同来源、分别具有不同专门化的文档组合起来,那么这种向上兼容性非常有用。
This upward compatibility is useful when you want to combine sets of documentation from two sources, each of which has specialized differently.
我已经提到过具有向上兼容性的XMLschema更新的问题,即不能检查新添加的元素和属性是否存在。
I've already mentioned the problem about evolving an XML schema with upward compatibility, where the existence of newly added elements and attributes cannot be checked.
使用向上兼容性更新XMLschema时需要考虑的一个问题是:XML数据具有新添加的元素和属性时不能通过验证。
A concern with evolving XML schema with upward compatibility is that XML data cannot be validated with the existence of newly added elements and attributes.
如果XMLschema被更新为与现有XML schema具有向上兼容性,则现有XML数据无需任何更改就可以通过新的XML schema进行管理。
If the XML schema is evolved as upward compatible with the existing XML schema, the existing XML data can be managed with the new XML schema without any modifications.
当XML数据更新为与现有 XML schema具有向上兼容性时,可以使用新的 XML schema来管理现有 XML 数据,无需任何修改。
When XML data is evolved which is upward compatible with the existing XML schema, you can manage the existing XML data with the new XML schema without any modification.
当XML数据更新为与现有 XML schema具有向上兼容性时,可以使用新的 XML schema来管理现有 XML 数据,无需任何修改。
When XML data is evolved which is upward compatible with the existing XML schema, you can manage the existing XML data with the new XML schema without any modification.
