XHTML验证，自定义名称空间和属性 [英] XHTML validation, custom namespaces and attributes
问题描述
我有一个客户要求XHTML有效的网站.他们使用W3C验证器对其进行检查.
I have a website that a client requires to be XHTML valid. They check it using the W3C validator.
我想添加自己的名称空间和属性，以便可以执行以下操作:
I want to add my own namespace and attributes so I can do things like this:
<div my:userid="123"> ... </div>
据我了解，只要我这样做，定义自定义名称空间就是完全有效的XHTML:
From what I understand, defining custom namespaces is perfectly valid XHTML, as long as I do this:
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:my="http://www.example.com/my">
但是，我的XHTML验证失败.问题似乎在于，验证器实际上并未退出并检查我的自定义DTD文档中的自定义名称空间，它仅对照已知的DTD来检查XHTML.任何人都可以阐明我如何解决这个问题?
However, my XHTML fails validation. The problem appears to be that the validator does not actually go out and check my custom DTD document for my custom namespace, it only checks the XHTML against known DTD's. Anyone able to shed any light on how I can solve this problem?
推荐答案
对于XHTML 1.0，您只能使用XHTML 1.0元素和属性:
For XHTML 1.0 you are restricted to XHTML 1.0 elements and attributes:
此版本的XHTML提供了严格符合标准的XHTML 1.0文档的定义，这些文档仅限于XML和XHTML 1.0名称空间中的元素和属性.
This version of XHTML provides a definition of strictly conforming XHTML 1.0 documents, which are restricted to elements and attributes from the XML and XHTML 1.0 namespaces.
我的理解是XHTML 2.0旨在提供一个框架来完成您想要做的事情.
My understanding is that XHTML 2.0 aims at providing a framework for doing what you want.
