Your last couple of messages seem to agree with (at least my
interpretation of) the spec.

description for "createEntityReference", it says that the implementation

I guess I was wrong in my original statement; HTML documents aren't
allowed to have entity references. However, full XML documents should be
allowed to have entity references, and so attribute nodes there should
allow child nodes that are entity references.

It does appear that current browser implementations do not fully support
this DOM functionality, and that just using .value and .nodeValue is
probably fine.

Agreed, that makes sense.
