I can't speak for Microsoft, but my guess is that they are simply using XML in the manner most analogous to objects in object oriented systems. In an object, the attributes are the data values: class Author { String name; // e.g. "Mr John Smith" }; Here they have used the name VALUE in a similar way: class Author { String VALUE; // e.g. "Mr John Smith" }; One very easy way to change objects into XML elements is to use one element for each object, and use attributes to model the data members: <author VALUE="Mr John Smith" >/> The reason attributes are better for this is that an object may have many data members, and these are distinguished by names. The element content only has one place to put things, and there is no name associated with it. >Is this simply just a design preference, or else is there a concrete >reason why what seemingly is content should be embedded as an attribute. To me, Microsoft's method makes sense if what you are doing is converting objects to XML, but your preferred method ("<author>Mr John Smith</author>") makes more sense if you are converting objects to XML and back.
