RE: [xml-dev] RE: When you create a markup language, what do yourparent elements mean? What do your children elements mean?

As with RelaxNG, the focus on the underlying model which can then be serialized in multiple ways.  For RDF, RDF/XML is just one of those options.  And using RDF/XML then enforces the striping pattern described.  Using something like Turtle (another option) is not based on XML and, therefore, does not serialize using elements/attributes.
