Actionscript xml validating schema

There are XML definitions for menus, graphics, directory listings, and so on.

As an example, the simplest XML object supported by the phone is the Cisco IPPhone Text element.

A well-formed document is one that follows the basic rules of XML regarding basic syntax, such as nesting of tags, placement of attributes, and so on.

Creating well-formed documents is fairly easy for developers, because you can simply add new elements and attributes as the need arises, confident that the parser reading the document will know what to do.

So, for example, XML Schema allows me to specify that a value between the tags should be a floating-point value between 1.0 and 9.99.

When the Cisco IP Phone attempts to render this XML object, its parser naturally rejects the input.In the early days of XML, these rules were typically defined in what was called a Document Type Definition, or DTD.For various reasons, the DTD format first used with XML proved to be unpopular, and a revised schema definition system called XML Schema was born.An additional boon was the support for XML in off-the-shelf tools, such as Microsoft’s Internet Explorer or Altova’s XML Spy.The menagerie of XML objects that the phone knows how to render and/or execute is fairly small.

Over the past few months I’ve been laboring away at a new book for Cisco Press which has the snappy title Developing Cisco IP Phone Productivity Services.
