Re: SAX2 RFD: LexicalHandler draft v.1.1

* David Megginson
|     public abstract void xmlDecl (String version,
| 				  String encoding,
| 				  String standalone)
| 	throws SAXException;

Should we perhaps make standalone a boolean instead?  It can only have
two values anyway, and this will spare us a lot of
standalone.equals(this or that).
|     public abstract void startDTD (String doctype,
| 				   String publicID,
| 				   String systemID)
| 	throws SAXException;

I think naming doctype docelem or rootelem would be better. It took me
a couple of seconds to figure out what it meant.
|     public abstract void startEntity (String name)
| 	throws SAXException;

Is this sufficient? Now we don't even know whether it's internal or
external. I know EntityResolver can be used to get that information
(including sysid and pubid), but I'd much rather see it included here
as well, since IMHO EntityResolver fills a separate role from the data
handlers. Often one would want to plug in a separate component there.

How about this?

      public abstract void startEntity (String name, String publicID,
                                        String systemID)
        throws SAXException;
If systemID is null we know it is an external entity. Alternatively,
we could have a separate callback for external entities.
