This is most likely coming from the Tidy HTML validator packaged with Aptana's version of Eclipse. If you open the preferences for your HTML browser within Aptana, you can add a regular expression to filter the validation errors.
这很可能来自与 Aptana 的 Eclipse 版本一起打包的 Tidy HTML 验证器。如果您在 Aptana 中打开 HTML 浏览器的首选项，您可以添加正则表达式来过滤验证错误。
This can be done by going to the Window > Preferences dialog window. Then, expand Aptana > HTML and select 'Validation'.
这可以通过转到“窗口”>“首选项”对话框窗口来完成。然后，展开 Aptana > HTML 并选择“验证”。
The filter would probably look like this:
过滤器可能看起来像这样：
.*<canvas> is not recognized.*
.*<canvas> 无法识别。*

The specific rule under the Aptana>Editors>HTML>Validation filter is
Aptana>Editors>HTML>Validation 过滤器下的具体规则是
.*<\s*canvas\s*> is not recognized.*
.*<\s*canvas\s*> is not recognized.*
Doing something more generic like .* is not recognized.*lets any Bad Tag in
做一些更通用的事情，比如.* is not recognized.*让任何坏标签进入

The answer, in clear terms, is to go to the HTML>Validation view under preferences as Malaxeursaid (for Aptana2 on OSX it was Aptana Studio>Preferences, then Aptana>Editors>HTML>Validation), and createa newrule that resembles the following.
答案，在明确的条款，是去HTML>下的喜好验证视图MALAXEUR说（为Aptana2 OSX上它的Aptana Studio的>首选项，然后集锦>编辑> HTML>验证），并创建一个新的规则类似于下列。
.* is not recognized.*
that's what worked for me. how or why it works, i can't explain.
这对我有用。它如何或为什么起作用，我无法解释。

The error will disappear if using the HTML5 doctype and a more recent version of Eclipse. I'm running Eclipse IDE for Java EE Developers (Build id: 20110218-0911) and do not have this issue.
如果使用 HTML5 文档类型和更新版本的 Eclipse，该错误将消失。我正在为 Java EE 开发人员运行 Eclipse IDE（构建 ID：20110218-0911）并且没有这个问题。

I think it's already fixed in the current Aptana 3 beta. But in Aptana 2 it's still a problem. To allow not all, but multiple HTML5 Tags you could do it with a filter rule like that:
我认为它已经在当前的 Aptana 3 beta 中修复了。但是在 Aptana 2 中它仍然是一个问题。要允许不是全部而是多个 HTML5 标签，您可以使用这样的过滤规则：
<(nav|header|section|article|canvas)> is not recognized.
Of course there are some more tags to consider. Just add the ones you need.
当然还有更多的标签需要考虑。只需添加您需要的那些。
