Re: [xml-dev] Does data represent things besides entities,attributes, and relationships?

The terms entities, attributes and relationships are categories
relevant to data modeling.  Depending on the purpose, you can
model the passage in question in many ways within the framework of
those categories.

Are there other kinds of things in the world that you want to
capture -- at that level?  Relational modeling has done well
enough with those notions.

Is there some other "level" that's appropriate?  I don't know --
is that where you're coming in?  Is there some reason why these
abstractions can't serve your purposes?
