1) it is undefined
2) use SGML processing and return the default entity if defined, null if not.
3) break with SGML and return the entity name.
I can implement all of the choices but I would like to get a reading on what
the HTML2 spec says I should do. This isn't a case of telling a browser how
to behave in an error condition since SGML defines what should happen with an
undefined entity. It looks like the HTML universe needs a different behavior
than the SGML standard and the spec should point this out.
For those of you who asked, I am working on an unreleased browser that has
been under development for about 18 months.
