1.3 Microsoft Implementations

  • Article

The [W3C-XML-StyleSheets] specification is implemented by Microsoft XML Core Services (MSXML) 3.0 (MSXML3) through Windows Internet Explorer 9, Windows Internet Explorer 10, Internet Explorer 11 and Internet Explorer 11 for Windows 10.

MSXML3 is used by Windows Internet Explorer 7, Windows Internet Explorer 8, Internet Explorer 9, Internet Explorer 10, Internet Explorer 11 and Internet Explorer 11 for Windows 10.

Windows Internet Explorer implements multiple document modes, which vary from one another in their support of the standard. Internet Explorer 9, Internet Explorer 10, Internet Explorer 11 and Internet Explorer 11 for Windows 10 use MSXML3 for Quirks Mode, IE7 Mode, and IE8 Mode. For IE9 Mode, IE10 Mode, and IE11 Mode, Internet Explorer provides built-in support for the [W3C-XML-StyleSheets] specification.

Throughout this document, variations and clarifications note whether they apply to MSXML3, IE9 Mode, or later modes. The document mode appears first followed by the browser version in parentheses. Only those document modes and browser versions for which there is a variation note will be listed. If the document mode is not listed, conformance to the specification can be assumed.
