I am the developer of an HTML checking tool. I want to check meta names to make sure they match case-sensitively when it matters. All I've come across so far (according to Google) is that this meta name ("google-site-verification") should be case sensitive as in:
<meta name="google-site-verification" content="XXX">
That is, you would not want to use this:
<meta name="GOOGLE-SITE-verification" content="XXX">
Are there any other meta names that are case-sensitive? I'd like to check for this in my tool.
UPDATE: Looks like Microsoft has many more that are case-sensitive, most of which are msapplication-*: http://msdn.microsoft.com/en-us/library/ie/dn255024.aspx
