Re: [Wikitech-l] Named entity references and XML well-formedness

In XML, named entity references like   and • (with the special exceptions of < > & " ') can be treated as well-formedness errors across the board by conformant XML processors. (Yes, this means that *any* XML document that uses *any* named entity reference except the special five is not well-formed, if you ask these XML processors.) Alternatively, if a DTD is provided, conformant XML processors can retrieve the DTD, parse it, and treat the reference as a well-formedness error if it doesn't occur in the DTD, otherwise parse it as you'd expect. (Yes, processors can really pick whichever behavior they want, as far as I understand it. As we all know, the great thing about standards is how many there are to choose from.)
