Editing Internet Explorer (section)

===Standards support===
Internet Explorer, using the MSHTML (Trident) [[browser engine]]:
* Supports [[HTML]] 4.01, parts of [[HTML5]], [[Cascading Style Sheets|CSS]] Level 1, Level 2, and Level 3, [[XML]] 1.0, and [[Document Object Model|DOM]] Level 1, with minor implementation gaps.
* Fully supports [[XSLT]] 1.0 as well as an obsolete Microsoft dialect of XSLT often referred to as ''WD-xsl'', which was loosely based on the December 1998 W3C Working Draft of [[Extensible Stylesheet Language|XSL]]. Support for [[XSLT 2.0]] lies in the future: semi-official Microsoft bloggers have indicated that development is underway, but no dates have been announced.
* Almost full conformance to CSS 2.1 has been added in the Internet Explorer 8 release.<ref>{{cite web | url = http://code.msdn.microsoft.com/ie8whitepapers/Release/ProjectReleases.aspx?ReleaseId=568 | title = Internet Explorer 8 Beta 1 Whitepapers | publisher = [[MSDN]] | access-date = March 11, 2008 | archive-date = March 9, 2008 | archive-url = https://web.archive.org/web/20080309001142/http://code.msdn.microsoft.com/ie8whitepapers/Release/ProjectReleases.aspx?ReleaseId=568 | url-status = dead }}</ref><ref>{{cite web|url=http://idreamincode.co.uk/ie8-bugs |title=IE8 Bugs |first=James |last=Hopkins |url-status=dead |archive-url=https://web.archive.org/web/20090801120753/http://idreamincode.co.uk/ie8-bugs |archive-date=August 1, 2009}}</ref> The MSHTML browser engine in Internet Explorer 9 in 2011, scored highest in the official W3C conformance test suite for CSS 2.1 of all major browsers.
* Supports [[XHTML]] in Internet Explorer 9 (MSHTML Trident version 5.0). Prior versions can render XHTML documents authored with HTML compatibility principles and served with a <code>text/html</code> [[MIME|MIME-type]].
* Supports a subset<ref>{{cite web| url = http://www.codedread.com/svg-support.php | title = Summary results of W3C test suite on multiple browsers, different versions and browser plugins. | access-date = April 15, 2011}}</ref> of [[Scalable Vector Graphics|SVG]] in Internet Explorer 9 (MSHTML Trident version 5.0), excluding SMIL, SVG fonts and filters.

Internet Explorer uses [[document type declaration|DOCTYPE sniffing]] to choose between standards mode and a "[[quirks mode]]" in which it deliberately mimics nonstandard behaviors of old versions of MSIE for HTML and CSS rendering on screen (Internet Explorer always uses standards mode for printing). It also provides its own dialect of [[ECMAScript]] called [[JScript]].

Internet Explorer was criticized by [[Tim Berners-Lee]] for its limited support for SVG, which is promoted by [[W3C]].<ref name="TBLcrit">{{cite web|url=https://www.nbcnews.com/id/wbna26646919|title=Creator of Web spots a flaw in Internet Explorer|last=Svensson|first=Peter|date=September 10, 2008|website=NBC News|access-date=November 16, 2008}}</ref>
