James has already provided a good answer.  Let me add some observation.

Digital signature people very much dislike default values of XML 1.0, because 
default values (which may be used or ignored) have impacts on digital 
signature.  If we introduce default values in RELAX NG, we make the situation 
even worse.  I think that programmers can easily hardcode "default values" 
in their programs or XSLT stylesheets.
