DotNetNuke Skins 文件夹中 XML Doctype 文件的用途是什么?

What is the purpose of the XML Doctype file in a DotNetNuke Skins folder?

我注意到 DNN 皮肤文件夹中有这个 XML 文件。这是否为 DotNetNuke 中的特定皮肤页面设置了文档类型?如果页面没有 XML 文件会怎样?

当我打开 XML 文件时,我注意到:

In the context of web pages,the doctype declaration refers to a Document Type Definition (DTD). The DTD specifies the rules for the markup language, so that the browsers can render the content follows the rules of that markup language i.e. different versions of the doctype render content in different ways.

In early versions of DotNetNuke the doctype was a fixed part of default.aspx and was set to "HTML 4.0 Transitional" which was not ideal for sites wanting to create valid XHTML markup. With 4.4, the declaration has been made dynamic, to allow users to declare particular doctypes with particular skins.
