URL 中的 HTML5 含糊不清的符号

Question

W3C Validator在我的一些 URL 中引发了关于 & 符号的错误。例如:

<link href="min/?f=static/css/reset.css,static/css/main5.css&2" rel="stylesheet">

根据HTML5 spec ，然而，验证器是错误的:

An ambiguous ampersand is a U+0026 AMPERSAND character (&) that is followed by one or more alphanumeric ASCII characters, followed by a U+003B SEMICOLON character (;), where these characters do not match any of the names given in the named character references section.

This site得出相同的结论，并指出目前没有验证者正确实现规范。

有什么确定的吗？

我相信你是对的 - 根据以下线程，这是 a bug in the HTML5 validator .我不知道这是否是“最终的”，因为它不是官方声明(但我认为回复中的名字至少是 SO 上知名成员的名字)。

您尝试执行的操作在 HTML5 中确实有效(在特定情况下，例如您的情况)。

以下是该错误报告的摘录以供引用:

"Simply, that & does not have to be escaped to &" - Source.

主题回答/解释:

That's right, in HTML5. It's a bug in the validator that it says otherwise, see http://lists.w3.org/Archives/Public/www-validator/2013Mar/0009.html. The unstable development version of the validator, http://qa-dev.w3.org:8888/ has this bug fixed (and your document validates in it).

This may, in part, reflect the nature of HTML5 validator as experimental software that checks against some "specification" which is not identified in public and which may change at any moment without notice and often does. - Source.
