- Comparison of layout engines (XML)
-
The following tables compare XML compatibility and support for a number of layout engines. Please see the individual products' articles for further information. This article is not all-inclusive or necessarily up-to-date. Unless otherwise specified in footnotes, comparisons are based on the stable versions without any add-ons, extensions or external programs.
Version number, if possible, is provided for feature that is fully supported. Proprietary extensions are not included.

Explanation of the tables
Engine nomenclature
Rather than the names of web browsers, the names of the underlying engines are used. The browsers that use the various engines are listed below.
Layout engine Release version Preview version Used by Amaya 11.3.1 11.3-pre Amaya Gecko 6.0.2 8.0a2 All Mozilla software, including Firefox; SeaMonkey and Galeon; Camino; K-Meleon; Flock (up to 2.x); Epiphany-gecko; Debian IceWeasel; GNU IceCat (formerly GNU IceWeasel); Icedove, Iceape and Iceowl; Fennec KHTML N/A Konqueror Presto 2.9.168 2.9.168 Opera; Opera Mobile, Nintendo DS & DSi Browser; Internet Channel Prince 7.1 N/A Prince XML Tasman (IE 5.2.3 for Mac) none (aborted in 2003) Internet Explorer 5+ for Mac OS X Trident 5.0 (IE 9) 6.0 (IE 10) Internet Explorer and other Internet Explorer shells like Maxthon (Microsoft Windows operating systems only), Windows Phone 7 WebKit 534.20 r83424 Safari (both desktop and mobile), Google Chrome, Maxthon 3, Shiira, iCab 4, OmniWeb 5.5+, Epiphany, Adobe AIR, Midori, Adobe Dreamweaver CS4 and CS5, Android browser, Palm webOS browser, Symbian S60 browser, OWB, Steam, Rekonq, Arora, Flock (version 3+), RockMelt Values
Values indicate the level of support in the most recent version of the layout engine, or (if a version number is given) in the specified version. Version numbers without any other value indicate the version at which the layout engine first fully supported the feature.
Value Meaning Yes Indicates that the layout engine fully supports this property/element when valid values are used. No Indicates that the property/element is completely ignored. Partial Indicates that the property/element is understood, but that not all values are supported. Supported values are implemented correctly. Incorrect Indicates that the property/element is understood, but that it is not implemented correctly in all cases. Experimental Indicates that the property/element is understood, but supported under an alternate name. May be incomplete or buggy. Dropped Indicates that the property/element is no longer supported. Nightly build Indicates that the property/element is supported to some extent in an experimental/nightly build. Future support is expected. Depends Indicates that the property/element is supported only on certain platforms, or if certain settings are configured. Core technologies

- ^ Trident relies on the MSXML library to implement XML processing. MSXML3 and MSXML4 implement XSLT 1.0, while MSXML2 implements the December 1998 XSL Working Draft, which predates XSLT 1.0 and is not fully compatible with it. Further complicating matters is that the MSXML libraries can coexist, but only one of them will be used by Trident, depending on a setting in the Windows Registry. Prior to the release of Internet Explorer 6, MSXML2 was the default XML library for Trident, but MSXML3 or MSXML4 could be installed separately and then registered as the default if desired. Regardless of which version was the default, any version, if installed, could be invoked directly by Microsoft-specific scripting code in the document being rendered by Trident.
- ^ Gecko as of version 1.8 upports only simple XLinks, and only for SVG and MathML.[g 4][g 5]
- ^ Prince XML supports only simple XLinks.[r 1]
- ^ Only inline DTDs are allowed, external DTDs are ignored.[g 8]
- ^ Prior to version 2.0, only inline DTDs are allowed; external DTDs are ignored. In 2.0, it is possible to load external DTDs, but not cross-domain.
