validation - 如何处理未在 HTML5 中验证的元元素？

Question

在 HTML5 中，一些元元素不验证(还？)像:

<meta http-equiv="x-ua-compatible" content="ie=emulateie7;chrome=1">
<meta http-equiv="imagetoolbar" content="no">

条件注释是这里的适当解决方案吗？元元素仍会按预期工作吗？

<!--[if IE]><meta http-equiv="x-ua-compatible" content="ie=emulateie7;chrome=1"><![endif]-->
<!--[if lt IE 7]><meta http-equiv="imagetoolbar" content="no"><![endif]-->

使用 .htaccess 文件而不是元元素(不幸的是，并不总是可行)，这是正确的方法吗？

<IfModule mod_setenvif.c>
  <IfModule mod_headers.c>
  # BrowserMatch MSIE ie OR?
    BrowserMatch MSIE emulate_ie7
  # Header set X-UA-Compatible "IE=EmulateIE7" env=ie OR?
    Header set X-UA-Compatible "IE=EmulateIE7" env=emulate_ie7
    BrowserMatch chromeframe gcf
    Header append X-UA-Compatible "chrome=1" env=gcf
  </IfModule>
</IfModule>

谢谢!

就“x-ua-compatible”标签而言，我选择了 .htaccess 指令。我关注了html5boilerplate模板:

# ----------------------------------------------------------------------
# Better website experience for IE users
# ----------------------------------------------------------------------

# Force the latest IE version, in various cases when it may fall back to IE7 mode
#  github.com/rails/rails/commit/123eb25#commitcomment-118920
# Use ChromeFrame if it's installed for a better experience for the poor IE folk

<IfModule mod_setenvif.c>
  <IfModule mod_headers.c>
    BrowserMatch MSIE ie
    Header set X-UA-Compatible "IE=Edge,chrome=1" env=ie
  </IfModule>
</IfModule>

<IfModule mod_headers.c>
# Because X-UA-Compatible isn't sent to non-IE (to save header bytes),
#   We need to inform proxies that content changes based on UA
  Header append Vary User-Agent
# Cache control is set only if mod_headers is enabled, so that's unncessary to declare
</IfModule>
