This is to announce the first public version of the DynamicDOM APIs along 
with a tutorial and sample code.

The DynamicDOM is an extension of the DOM with the ability to enforce and 
execute XRules business rules. With the DynamicDOM you can load your XML 
purchase order, attach your business rules document to it, and then update
the ItemQuantity node just to find that the SubTotal, Tax, and GrandTotal 
nodes get updated automatically based on the rules you specified.

DynamicDOM is implemented in the class DXmlDocument which is inherited from 
the .NET XmlDocument class. And, a command-line utility is available for 
non-.NET applications.

A tutorial and C# code is available for download from:
http://www.xrules.org/


The DynamicDOM extends the DOM by adding new APIs for managing XRules 
documents, editing Infoset properties, and capturing DynamicDOM events. The 
API set is simple and easy to learn. For example, to apply XRules to an XML 
document all you need to do is:

    myXml.XRulesDocuments.Add("myXRules.xr");

That's it; the rules are applied, some XML nodes have new values now, and 
some validation errors are already in the Errors collection. Have fun.

About XRules:
XRules is an XML business rules language that expresses constraints, 
calculations, interdependencies, and properties that describe and exist 
among elements and attributes of an XML document. XRules can be used to 
validate business rules in an XML transaction, attach metadata to the XML 
Infoset, or add dynamism to XML by using the DynamicDOM.
