Comparison of layout engines (XML)
From EverybodyWiki Bios & Wiki
The following tables compare XML compatibility and support for a number of browser engines.
Explanation of tables[edit]
See comparison of browser engines for the full list.
Values[edit]
These indicate the level of support for the given item in each engine. By default, the most recent version of the engine is implied. However, a specific version number can be listed; when this indicates full support, it's the initial version of the engine fully supporting the item.
| Value | Meaning |
|---|---|
| Yes | Fully supported |
| No | Has never been supported |
| Partial | Only some values are supported |
| Incorrect | Not implemented correctly in all cases |
| Experimental | May be incomplete or buggy |
| Nightly build | Currently in development; full support is expected |
| Depends | Only supported for the specified conditions |
| Dropped | No longer supported |

Notes[edit]
- ↑ MSHTML 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 MSHTML, depending on a setting in the Windows Registry. Prior to the release of Internet Explorer 6, MSXML2 was the default XML library for MSHTML, 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 MSHTML.
- ↑ Gecko, as of version 1.8, only supports simple XLinks, and only for SVG and MathML.[g 4][g 5]
- ↑ Prince 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.
