From the pattern: "This pattern contains XML untyped by DTD or schema, but follows accessors for underlying
program objects. It allows for unlimited extension by multiple, uncoordinated parties at the cost of lack
of type-checking; and is simple to implement, with supporting libraries abounding
(e.g. Apache Commons for Java; .NET's XML marshalling for C#)."
This pattern is from Kyle Downey's article Architectural Design Patterns for XML Documents.
The pattern fits well with the Document Root Category
of patterns presented on XMLPatterns.cm
