By the way, if you really want to do this, you can technically make undefined entities not be well-formedness errors by using a trivial DTD that refers to a parameter entity, e.g. <!DOCTYPE foo [ <!ENTITY % dummy "<!-- a comment -->"> %dummy; ]> <foo>this document is &well-formed;</foo> Undefined entity references are only well-formedness errors when a minimal parser can be sure that there is no unread declaration; since minimal parsers do not have to process parameter entities, they cannot be relied on to know that there is not a declaration in the parameter entity. Of course this only gives you a warm fuzzy feeling; it does not guarantee that current parsers won't reject the document. -- Richard
