What is the difference between content = "IE = 7; IE = 9" and content = "IE = 7, IE = 9"

In my HTML, I used a meta tag as shown below for some font issues. I just want to know:

Are these meta tags the same? Or is everyone different?

<meta http-equiv="X-UA-Compatible" content="IE=7, IE=9" />

[comma separated]

<meta http-equiv="X-UA-Compatible" content="IE=7; IE=9" />

[separated by semicolons]

Please explain this.

Correct form as Microsoft on MSDN uses a halftone line instead of a single comma:

<meta http-equiv="X-UA-Compatible" content="IE=7, IE=9" />


Here's a snippet of text:

Note. [...] You can also use the content attribute to specify multiple document compatibility modes; this helps to ensure that web pages are consistently displayed in future browser versions. Specify multiple document modes, set a content attribute to identify such modes of use. Use semicolon to separate modes together.
