Microsoft has recently changed their examples to use lowerCamelCase attributes
instead of elements for "properties".  Here's the example from the Document
Design Guide you quoted above:

And here's a similar example from a more recently published BizTalk Framework
Document Specification 1.0 
(http://206.132.62.135/Biztalk%20Framework%20Document%20Specification%201.0.doc):

Personally, I prefer UpperCamelCase for both element and attribute names.
