Mike this looks good to me. I will incorporate it into errata v011.

Small revision to consolidate Simple and Complex absent rep.

Hi Mike 

Your changes look good. 

Re your TBD.  I don't mind whether we collapse ComplexAbsentElementRep and 
SimpleAbsentElementRep into a single term AbsentElementRep.

I've attached version 006. I added an important top-level distinction. 
Only "enclosed" elements can be absent. A top level document element 
cannot be absent.

Attached revised grammar 005 - proposed as "to become an errata".

I've made some updates which I think solves the complex empty issue, ties 
the grammar more closely to the action 140 rep definitions, and addresses 
Tim's content v value distinction. 

Let me know what you think.

Accept-all-changes on that document before you try to read it.  Or use the 
attached.

I took a crack at revising the grammar to something more accurate, more 
useful. It's bigger, but not 3 times as big.

I like it, but then I'm an implementor, not a user of this spec trying to 
devise a schema.  Our audience is both however.

I am curious what you think. 

One thing it cannot capture is the complexity of complex empty's, i.e., 
the fact that a complex empty requires one to sometimes descend 
recursively first, and then check for empty. From the grammar you would 
think you can always check for this first.

Fact is, you have to descend recursively in order to pop back up, and have 
the representation be found to match what I call EmptyElement. But the 
grammar can't show that. (well, maybe it could... I'll think about that 
further.)
