为此，ext4被设计为在extent方面具有向后和向前兼容性(参见图1)。

松散——所有不兼容的更改导致服务契约的新版本，且服务契约的设计既支持向后兼容，也支持向前兼容。

因为不能修改以前的代码(否则该代码就是一个新应用程序了)，所以必须从一开始就包括向前兼容性。
You cannot change the old code (otherwise it becomes a new application), so you must include forward-looking compatibility from the outset. Specifically, the code must.
所有XSLT处理程序，包括1.0处理程序都必须支持向前兼容(FC)，即样式表的版本号高于当前处理程序版本。
All XSLT processors, including 1.0 processors, are required to support Forwards Compatibility (FC), which is where the version number on the stylesheet is higher than the version of the processor.
COM互操作还使COM客户端能够像访问其他COM对象一样方便地访问托管代码，从而提供了向前兼容。
Com interop also introduces forward compatibility by enabling your com clients to access managed code as easily as they access other com objects.
尽管可以创建直接实现IBridge的连接器，但是强烈建议您扩展BaseBridge，从而保持向前兼容性。
Although it's possible to create a connector that implements IBridge directly, it's strongly recommended that you extend BaseBridge to preserve that forward compatibility.
向后兼容(BC)和向前兼容(FC)方式都是通过version属性触发的，而不是处理程序开关或者启动选项。
Backwards compatibility (BC) and FC modes are always triggered by the version attribute, not by any processor switch or launch-time option.
由于获得向前兼容性很重要，也比较困难，所以XMLSchema 1.1中的主要目标之一就是让编写向前兼容的模式更为容易。
Because of the importance and difficulty in achieving forward compatibility, one of the major goals in XML schema 1.1 is to make it easy to write forward compatible schemas.
这是大多数Web媒体类型长期以来的工作方式，成功程度各有不同。但是，要注意，那些格式都是经过考虑了向前兼容的长远的设计定义的。
It's the way that most web media types have long worked, with varying degrees of success, but note that those formats were long designed with forward compatibility in mind.
注：这里的“向后兼容”和“向前兼容”在第16章的兼容性变更(Compatible Change, 465)里有具体介绍。
Note - the terms "backwards compatibility" and "forwards compatibility" are explained in the description for Compatible Change (465) in Chapter 16.
XSLT 2.0 中的文字看起来可能和这个具体的例子无关，因为 1.0处理程序按照 XSLT 1.0规范的要求自然要实现向前兼容。
The text in XSLT 2.0 might seem irrelevant for this particular example, since a 1.0 processor naturally implements the FC behavior as dictated by the XSLT 1.0 specification.
USB 3.0向前与旧版本usb标准兼容么？
可使用use-when属性进行向前和向后兼容处理。
The use-when attribute can be used for forwards and backwards compatibility processing.
Beck和Gamma努力维持向前和向后兼容。

例如，如果将XML用作数据交换标准，应用程序必须提供向前和向后兼容性，以支持较新或较旧的版本标准。
For example, in the case where XML is used as a standard for data exchange, the application must provide backward or forward compatibility to older or newer versions of the standard.
Ext4文件系统被设计为具有向前和向后兼容性，但它具有许多新的高级特性(其中的一些特性破坏了兼容性)。
The ext4 file system is designed as a backward - and forward-compliant replacement for ext3fs but with many new advanced features (some of which break the compatibility).
Ext4文件系统被设计为具有向前和向后兼容性，但它具有许多新的高级特性(其中的一些特性破坏了兼容性)。
