All the browsers return an error for named entities other than the five predefined entities. It is not valid, because there is no DTD for XHTML5. No DTD, no external entities. Anything else, would result in non-conforming XML documents. This discussion seems to be focused more on how browsers respond when they discover a named entity for a doctype that's not in the blessed list. I don't know if this was Alexey's original concern, but that's where it has evolved. > However, it might be that the specification of these things does not need to > go into the HTML 5 specification itself. > > Regardless, whenever and wherever it becomes been specified, the quote above > would need to be updated . > -- > leif halvard silli > Shelley
