XML appears as innovation slows

The browser wars have quieted

A reaction to 'tag soup' The 'browser wars' were a period of intense development for HTML, as competing vendors attempted to reach developers by providing them with every tool they might want. The results were messily incompatible, and competition proved ruinous for at least one of the contenders. XML offered the chance for developers to pick their own tools.
However... Microsoft Microsoft has contented itself with partial implementation of XML browsing technologies in Internet Explorer, facing relatively little competition from Netscape and Opera. Its latest browser doesn't yet integrate their latest (compliant) XSLT processor.
while... Netscape Netscape is still in Preview Release on its much-delayed Netscape 6 browser, which implements XML, the DOM, and more of CSS.
and... Opera Opera's recent version 4 browser expands its support for XML, CSS, and the DOM considerably, though it isn't as complete as Netscape and is missing support for character encodings required by XML 1.0.
