Emile for Mac

From Media Design in•Progress:

Emil is a highly customizable XML editor that supports productive markup with XML, liberating the author from detailed knowledge of the XML specification by providing context-sensitive dialogs and menus listing allowed tags and common markup constructs. The editor automatically adapts the user interface to the current document type (DTD), and comes with a validator to ensure correct markup.Emil includes a powerful text editor that is specialized for extensible markup, making the application a suited companion for learning from the many books and articles that present XML in text format. Palettes display the document outline and element context so that authors can see the hierarchical structure of the content. Emil comes with an optional Validator to ensure correct markup, and can be extended with other plug-in components.Extensible Markup Language (XML) is an open document standard for structured content, created by the World Wide Web Consortium (W3C) for use on the World Wide Web, vendor-neutral data interchange, media-independent publishing, collaborative authoring, and processing of web documents by intelligent agents. XML allows authors to use custom elements and other specialized markup constructs, making content more flexible and reusable.Internet Explorer 5.0 supports XML, and so will the next version of Netscape Navigator. Emil Lite can export an XML document as HTML, so web authors can take advantage of extensible markup while keeping the pages accessible for older web browsers.The W3C has announced that the next version of HTML will be based on XML.
