I expect that this is one of the questions that Simon will be asking :-) I
think when I started I had assumed that we might wish to argue for your
example. It might then get translated automatically into:

<!ENTITY greetings.content "#PCDATA">
<!ELEMENT greetings (&greetings.content)>

Whereupon the parser takes over. I had simply suggested that the parser
could operate at an earlier stage.  I expect that Simon will guide us
through this :-) and I would expect a question like:

"Do we wish to define entities in an XSchema?"
