版本、兼容性以及标准 续（翻译）

续前半部分。

Commitment to Standards and Interoperability
对于标准和互操作性的承诺

Yet another reason we feel more mode switches are not a good idea for WebKit is our commitment to Web standards, and to interoperability with other browsers. We strongly believe that Web standards are the path forward for interoperability, and we work closely with Web standards groups and other browser vendors to align behavior.
我们认为对于WebKit来说更多模式切换不是好主意，还有另一个原因，那就是我们对于Web标准的信仰，以及我们对于与其他浏览器的互操作性的承诺。我们坚定的相信，Web标准是通向互操作性之路，并且我们与Web标准团体和其他浏览器厂商紧密合作，以统一浏览器的行为。

Part of this commitment is delivering standards-compliant behavior out of the box. We don’t ask you to set a special preference, or to add extra markup to your web page, or anything else beyond the long established standards mode switch. That means WebKit can truly pass standards-based tests like Acid2 and someday the forthcoming Acid3, and we’ll work more like other standards-based browsers over time. In general, web developers are happy to get automatic ever-advancing standards support from our engine, and indeed our support for advanced CSS3 properties has unleashed a wave of creativity in iPhone web apps.
让遵循标准的行为即时可用，也是这一承诺的应有之义。我们不会要求你设置特别选项，或是在你的网页中加入额外标记，除了已经存在的标准和怪癖模式切换之外，我们不会要求你做任何其他额外的事情。这意味着WebKit能真正的通过基于标准的测试，如Acid2和未来的Acid3，我们也会与其他基于标准的浏览器逐步趋向一致。总的来说，web开发者乐于从我们的引擎获得自动不断提升的标准支持，事实上我们对于高级CSS3特性的支持已经在iPhone的web应用中释放了巨大的创造力。

Reducing Engine Fragmentation
减少引擎的散乱

Another key reason to avoid more modes is to reduce the number of different compatibility profiles that web content authors have to deal with. With many different vendors shipping WebKit-based products, we rely a lot on the fact that uptake of WebKit-based browsers is really fast. Already many web developers are focusing primarily on Safari 3 and not Safari 2, because in only a few months the majority of users have upgraded.
应避免更多模式的另一个关键原因，是为了减少web内容创作者所需面对的不同兼容性配置方案（profile）的数量。随着许多不同的厂商采用基于WebKit的产品，市场对于基于WebKit的浏览器接受很快。已经有许多web开发者主要为Safari 3而不是Safari 2做开发，因为在很短时间内大多数用户就已经升级。

But locking in compatibility would mean you have to think about the compatibility profiles of old browsers a lot longer. And no one wants to think about the state of the engine in Safari 2 - I sure don’t! We made thousands of fixes and improvements and those fixes deserve to stick.
而兼容性锁定意味着你必须更长久的考虑旧浏览器的兼容性配置方案。没有人想去考虑Safari 2中引擎的版本状况——至少我不想。我们已经做了数以千计的修补与改进，它们可不好对付【这句意思吃不准】。

We Don’t Really Need It
我们并不很需要它

Finally, while we sympathize with the tough road that the IE team has to travel to achieve a high degree of standards compliance, we haven’t really experienced the same problem. The IE team has mentioned severe negative feedback on the IE7 release, due to sites expecting standards behavior from most browsers, but IE6 bugs from IE.

最后，我们理解IE团队为了做到高度遵循标准，需要经历艰难之旅，不过我们自己并没有这样的问题。IE团队提到了IE7发布后严重的负面反馈，这是因为对于大多数浏览器，网站期待的是符合标准的行为，唯独对于IE，网站期待的是IE6的bug。

But WebKit already has a high degree of standards compliance. And we are not in the enviable but tough position of being the most widely used browser. The fixes we do for standards compliance rarely cause widespread destruction, and when they do, it’s often a sign that the standards themselves may need revision. We do not get complaints from web content authors about their sites breaking, on the contrary we get a lot of praise for each version of the engine handling web sites better.
WebKit已经高度遵循标准了。我们也没有像最广为使用的浏览器那样，处于令人羡慕却又进退两难的位置。我们为遵循标准而做的修改极少会造成广泛的破坏，而且如果产生破坏，那往往说明标准本身需要修订。我们没有从web内容创作者那儿听到网站坏掉的抱怨，相反，我们得到了大量的赞扬，称赞我们每个引擎版本都能使网站变得越来越好。

Conclusion
结论

So, in conclusion, we don’t see a great need to implement version targeting in Safari. We think maintaining multiple versions of the engine would have many downsides for us and little upside. The IE team is, of course, under different constraints and free to make their own choices.
所以，结论是，我们并没有发现有必要在Safari中实现版本目标（version targeting）。我们认为维护引擎的多个版本对我们来说是弊大于利。当然，IE团队处于不同的约束条件下，自然可自行作出他们自己的决策。

我很少用safari，国内的垃圾站点太多！
但惊喜的是，我做的网页在safari上一次性测试通过，没有半点错误的解析出发生

虽然safari是我觉得最酷的浏览器，不过他这样的声明让我觉得他非常像是一个专为web开发者而设计的浏览器，IE的客户群毕竟远远超过了web开发者。
